Highlights Crystallites sizes of nanoparticles synthesized via ultrasound irradiation were less than 40nm. Ms and Hc of nanoparticles obtained at 25℃ were higher than at 50℃ under the same power. The samples exhibited the highest Ms at 25℃ and the lowest Hc at 50℃ both for 60W. The ultrasonic irradiation had a positive effect on improving the ferrite magnetic properties.

“…Among these three types, mixed ferrites are considered significant materials because of their wide range of tunability in properties. In recent decades, several investigations have been done to explore and enhance the magnetic and electrical properties of end member ferrites by substituting different divalent and trivalent cations using various synthesis methods [ 16 , [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] , [29] , [30] , [31] , [32] , [33] , [34] ]. Among the spinel ferrites, the Zn substituted ferrites are attracted special interest due to the strong tetrahedral site preference of Zn 2+ ion.…”

This paper reports the structural, morphological, spectroscopic, dielectric, ac conductivity, and impedance properties of nanocrystalline Mn 1-x Zn x Fe 2 O 4 . The nanocrystalline Mn–Zn ferrites were synthesized using a solvent-free combustion reaction method. The structural analysis using X-ray diffraction (XRD) pattern reveals the single-phase of all the samples and the Rietveld refined XRD patterns confirmed the cubic-spinel structure. The calculated crystallite size values increase from 8.5 nm to 19.6 nm with the Zn concentration. The surface morphological analysis using field emission scanning electron microscopy and the transmission electron microscopy confirms the nano size of the prepared ferrites. X-ray photoelectron spectroscopy was used to study the ionic state of the atoms present in the samples. Further, the high-resolution Mn 2p, Zn 2p, Fe 2p, and O 1s spectra of Mn 1-x Zn x Fe 2 O 4 does not result in the appearance of new peaks with Zn content, indicating that the Zn substitution does not change the ionic state of Mn, Zn, Fe, and O present in nanocrystalline Mn 1-x Zn x Fe 2 O 4 . The investigated electrical properties show that the dielectric constant, tan δ and ac conductivity gradually decrease with increasing Zn substitution and the sample Mn 0 · 2 Zn 0 · 8 Fe 2 O 4 has the lowest value of conductivity at 303 K. The ac conductivity measured at different temperatures shows the semiconducting nature of the ferrites. The impedance spectra analysis shows that the contribution of grain boundary is higher compared with the grain to the resistance. The obtained results suggest that the Zn substituted manganese ferrite nanoparticles can act as a promising candidate for high-frequency electronic devices applications.

“…Recently, spinel-structured ferrite nanomaterials, a type of general magnetic nanomaterials, have attracted the great attention of researchers and scientists. 14 − 18 Spinel ferrite containing M II Fe 2 O 4 (where M II = Co 2+ , Ni 2+ , Zn 2+ , Mn 2+ , and so on) shows noteworthy physicochemical properties. 19 − 24 Among spinel ferrites, cobalt spinel ferrite (CoFe 2 O 4 ) is important from the biomedical application perspective because of its great saturation magnetization, high permeability, and no favored direction of magnetization.…”

Oleic acid-coated cobalt ferrite nanoparticles were synthesized using the chemical co-precipitation route and characterized by standard techniques for structure, morphology, and magnetic properties analysis. The Rietveld refined X-ray diffraction (XRD) pattern of CoFe 2 O 4 nanoparticles indicated the formation of a cubic-spinel single-phase structure with the F d 3̅ m space group. The average crystallite size (∼12 nm) confirmed the nanocrystalline appearance of the prepared CoFe 2 O 4 nanoparticles. Transmission electron microscopy (TEM) images revealed the spherical nature of both (CoFe 2 O 4 ) and (OA-CoFe 2 O 4 ) samples. The absorption bands in the Fourier transform infrared (FT-IR) spectrum at ∼3418, 3026, 1628, 1404, 1068, 845, 544, and 363 cm –1 affirmed the spinel ferrite formation and OA attachment. The M–H curve recorded at room temperature showed the superparamagnetic nature of the CoFe 2 O 4 nanoparticles with moderate saturation magnetization (∼78 emu/gm). The blocking temperature of the prepared CoFe 2 O 4 nanoparticles obtained from the field-cooled and zero-field-cooled (FC–ZFC) curve was estimated to be 144 K. Further, the characterized surface-modified CoFe 2 O 4 was then added in ethylene glycol/water with various concentrations and characterized by the induction heating technique for the evaluation of their self-heating characteristics. A series of temperature versus time measurements were made by varying the ethylene glycol/water proportion for better understanding of the self-heating characteristics of the prepared CoFe 2 O 4 nanoparticles. All of the findings display the applicability of the surface-modified CoFe 2 O 4 nanoparticles in magnetic fluid hyperthermia toward noninvasive cancer treatment and other bio-applications.
