“…Multiferroic Aurivillius-type materials can find potential electronic and spintronic applications, for example as the random access memory [5,6]. The interesting applications of ceramic materials that exhibit simultaneously magnetic, ferroelectric or ferroelastic ordering can be their use to make magnetic sensors, data storage, capacitor or digital memories [7][8][9][10][11].…”

Aurivillius-type ceramics Bi 6 Fe 2−x Mn x Ti 3 O 18 x = 0, 0.3, 0.9, 1.5 were obtained by a solid-state reaction method using high-purity TiO 2 , Bi 2 O 3 , Fe 2 O 3 and Mn 2 O 3 powders. The milled powder was calcined at 1113 K for 4 h. After calcination, the powder was milled again than pressed into pellets and sintered at 1213 K for 4 h. It was detected that the addition of manganese ions to the multiferroic five-layer Aurivillius-type structure affects the size of the grains. It was found that, the certain amount of manganese ions causes that the polarization of the material doped by them, have the direction opposite to the direction of the applied electric field. The doped material behaves like dia-electric material. The presented research complements the research concerning the Aurivillius ceramics doped with manganese. An attempt was made to explain the reasons for the negative values of dielectric constant and dielectric loss, that occur in manganese-doped five-layer Aurivillius type ceramics and which have not been described in the literature so far.

“…As there is a coupling between ferroelectric and ferromagnetic properties in these materials, they are highly important for different future applications, such as stretchable antenna, magnetic memory elements, microelectronic devices, spintronics, information storage, signal processing, transducers and other compact size components. For further readings about multiferroic composite materials in detail, we refer the readers to the different reviews [104,105,106].…”

The Ba(1−x)CaxZryTi(1−y)O3 (BCZT), a lead-free ceramic material, has attracted the scientific community since 2009 due to its large piezoelectric coefficient and resulting high dielectric permittivity. This perovskite material is a characteristic dielectric material for the pulsed power capacitors industry currently, which in turn leads to devices for effective storage and supply of electric energy. After this remarkable achievement in the area of lead-free piezoelectric ceramics, the researchers are exploring both the bulk as well as thin films of this perovskite material. It is observed that the thin film of this materials have outstandingly high power densities and high energy densities which is suitable for electrochemical supercapacitor applications. From a functional materials point of view this material has also gained attention in multiferroic composite material as the ferroelectric constituent of these composites and has provided extraordinary electric properties. This article presents a review on the relevant scientific advancements that have been made by using the BCZT materials for electric energy storage applications by optimizing its dielectric properties. The article starts with a BCZT introduction and discussion of the need of this material for high energy density capacitors, followed by different synthesis techniques and the effect on dielectric properties of doping different materials in BCZT. The advantages of thin film BCZT material over bulk counterparts are also discussed and its use as one of the constituents of mutiferroic composites is also presented. Finally, it summarizes the future prospects of this material followed by the conclusions.

“…Shape and size of UPION depend on synthesis procedure of nanoparticles which ultimately effects the bio-distribution contrast of these particles in medical imaging applications. The common diamagnetic materials are water, wood and most organic compounds [5][6][7][8][9][10]. Electrons are arranged in energy states of successive order, and for each energy state there can only be two electrons of opposite spins as established by Paul's principle.…”

“…Even though the substance is composed of atoms that have no net magnetic moment (paired electrons), it reacts in a particular way to an applied field. Wilhelm Weber and Paul Lange in theorized that an applied field acts on a single electron orbit to reduce the effective current of the orbit, in turn producing a magnetic moment that opposes an applied field [6,9].…”

“…So, nanosized Biomagnetic nanoparticles (ranges from 1 to 100 nm) have attracted core focus of researchers in the biotechnological fields to their importance. Therefore, these materials based on the interaction with the external magnetic field are divided into 3 categories like: diamagnetism, paramagnetism, ferro and antiferromagnetism [5][6][7][8][9]. Diamagnetism refers to a material that exhibits a negative magnetism.…”

Nanotechnology is a multidisciplinary branch of science which encompasses numerous diverse fields of science and technology, ranging from biomedical, pharmaceutical, agricultural, environmental, advanced materials, chemical science, physics, electronics, information technology, and so on. Physical and Chemical properties as a major advantages of Nanoparticles can be used in various applications from Industries to medicine. Besides, Magnetic nanoparticles for medical applications have been developed by many researchers. In recent decades, it has received attention by virtue of their potential for applications in different fields. Due to several advantages and widespread applications of magnetic Nanoparticles in biotechnology, medical, material science, engineering, and environmental areas, much attention has been paid to the synthesis of different kinds of Biomagnetic nanoparticles (BMNPs). Core-shell nanoparticles include of coated various materials like: biopolymers (Chitosan, PAA) and bioceramics (Hydroxyapatite) as a shell on top of them and different hard and soft materials like metal oxide (Iron oxide and Cob alt composite) as a core. Improved properties of core-shell nanoparticles like less cytotoxicity, increase biocompatibility, decrease in an interactions with biomolecules, increase physicochemical stability and sort of that, can be due to their use in biological applications. After reviewing several research and review articles and synthesis procedure of Iron based Bio-magnetic Nanoparticles (BMNPs), we should emphasize that, It can be used in different applications like magnetic resonance imaging (MRI), drug delivery systems (DDS), immunoassay, also specially in diagnosis and treatment of cancer via hyperthermia (heat therapy) method.
