“…The analysis of several multinuclear different metal systems that show a slow relaxation of magnetization and magnetic hysteresis below the blocking temperature (TB), without undergoing 3D magnetic ordering, has paramount importance in the area of molecular magnetism that depends upon coordination complexes. One prominent example is iron oxide-based materials that exhibit huge magnetocrystalline anisotropy, high Curie temperature, relatively large magnetization and also have excellent chemical stability and corrosion resistivity as reported by Trukhanov et al [1][2][3][4][5][6][7][8]. These nanomagnets, called SMMs [9], are extremely important for magnetic information storage and quantum computing [10][11][12][13].…”

A new four-coordinated high-spin Co(II) complex was synthesized through the reactions of Co(NSC)2 with bathocuproine, by the diffusion method, resulting in an infinite one-dimension chain. Both static and dynamic magnetic properties were measured. The magnetic properties investigation shows that the single CoII ion properties dominate the magnetic behavior in the complex. Despite the presence of a four-coordinated single CoII ion, no SMM properties were exhibited by the complex.

“…1,2 Ferrite-based compounds are among the highest potential materials that could display excellent magnetic and dielectric properties simultaneously. [5][6][7][8][9] Recently, composites of multiphase and multiferroics materials have attracted considerable attention thanks to its uniqueness to possess both ferroelectric and ferro-or ferrimagnetic phases. 10 This exceptional possession permits them to control the magnetic field using an electric field, and vice versa, hence making them able to detect spontaneous polarization owing to spontaneous magnetization through a large coupling interaction.…”

Two phase-based nanocomposites consisting of dielectric barium titanate (BaTiO 3 or BTO) and magnetic spinel ferrite Co 0.5 Ni 0.5 Nb 0.06 Fe 1.94 O 4 (CNNFO) have been synthesized through solid state route. Series of (BaTiO 3 ) 1x + (Co 0.5 Ni 0.5 Nb 0.06 Fe 1.94 O 4 ) x nanocomposites with x content of 0.00, 0.25, 0.50, 0.75, and 1.00 were considered.The structure has been examined via X-rays diffraction (XRD) and indicated the occurrence of both perovskite BTO and spinel CNNFO phases in various nanocomposites. A phase transition from tetragonal BTO structure to cubic structure occurs with inclusion of CNNFO phase. The average crystallites size of BTO phase decreases, whereas that for the CNNFO phase increases with increasing x in various nanocomposites. The morphological observations revealed that the porosity is highly reduced, and the connectivity between grains is enhanced with increasing x content. The optical properties have been investigated by UV−vis diffuse reflectance spectroscopy. The deduced band gap energy (E g ) value is found to reduce with increasing the content of spinel ferrite phase. The magnetic as well as the dielectric properties were also investigated. The analysis showed that CNNFO ferrite phase greatly affects the magnetic properties and dielectric response of BTO material. The obtained findings can be useful to enhance the performances of magneto-dielectric composite-based systems.

“…The size-dependent abilities of nanoparticles include electronic, magnetic, optical, and chemical substance characteristics. Nanoparticles can be crystalline or amorphous [5].Nanosized ferrites could be prepared by many methods, including mechanized milling, ultrasonic cavitation method, radio rate of recurrence plasma, hydrothermal technique, reverse micelle method, sol-gel technique, citrate precursor, and co-precipitation technique [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. It is advisable to possess a synthesis method that allows for governor on the nanoparticle dimension and produces nanoparticles having a significant size distribution [2].…”

A pure ferrite and epoxy samples as well as the epoxy/ferrite composites with different 20 wt.%, 30 wt.%, 40 wt.%, and 50 wt.% weight ferrite contents have been prepared by the chemical co-precipitation method. AC-conductivity and dielectric properties such as the dielectric constant and dielectric loss of the prepared samples have been studied. The obtained results showed that the samples had a semiconductor behavior. The dielectric constant of the composites has been calculated theoretically using several models. For the composite sample that contains 20 wt.% of ferrites, these models give satisfactory compliance, while for the composite samples with a higher percentage of nanofillers, more than 30 wt.% theoretical results do not coincide with experimental data. The investigated polymer has very low conductivity, so this type of polymer can be useful for high-frequency applications, which can reduce the losses caused by eddy current. Thus, the prepared samples are promising materials for practical use as elements of microwave devices.Nanomaterials 2020, 10, 492 2 of 16 Nanotechnology can be an excellent tool in the study, preparation, research, and use of new perspective materials, as well as in solving the problem of particles sizes in the range of 1-100 nm, where unusual phenomena allow new applications [2][3][4]. Tiny nanoparticles with diameters of some nanometers usually look like molecules. Therefore, the atomic and electronic structures of such small nanoparticles possess different features, certainly not the same as those of the bulk materials. The size-dependent abilities of nanoparticles include electronic, magnetic, optical, and chemical substance characteristics. Nanoparticles can be crystalline or amorphous [5].Nanosized ferrites could be prepared by many methods, including mechanized milling, ultrasonic cavitation method, radio rate of recurrence plasma, hydrothermal technique, reverse micelle method, sol-gel technique, citrate precursor, and co-precipitation technique [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. It is advisable to possess a synthesis method that allows for governor on the nanoparticle dimension and produces nanoparticles having a significant size distribution [2]. The chemical substance co-precipitation method is the most excellent ideal for the formation of nanoparticles due to its ease and much-improved handle over the crystallite dimension and other qualities of the components [22]. Also, lately, magnetic composites comprising magnetic materials alongside polymers comprise a new era of multifunctional components that mix the properties from the constituents; these components are known as magneto-polymeric components [23].The characteristics of ferrites are highly susceptible to methodical handling, sintering conditions, and impurity. Nickel-zinc ferrite is one of the first widely used ferrite produced for an open range of applications that recognizes to high saturation magnetization, high resistance, high Curie temperature, high chemical stability, low coerciv...
