Development of MnZn ferrites by combinatorial synthesis and high throughput screening method

Effects of Ta2O5 addition on the microstructure and temperature dependence of magnetic properties of MnZn ferrites

“…So, the value and variation of temperature dependence of P cv are opposite to the value and temperature dependence of the initial permeability. Compared with the results of literature [17], the sample with 0.04 wt% Ta 2 O 5 of our study has higher magnetic performance in higher magnetic flux density and wider temperature range.…”

Enhancement of electrical and dielectric properties of Cr doped BaZn2 W-type hexaferrite for potential applications in high frequency devices

“…order effect [5]. MnZn ferrites with improved magnetic properties are synthesized for potential usage at wide frequency and temperature ranges [6]. Polycrystalline W-type hexagonal ferrites are good magnetic semiconductors with low electrical conductivity as well as low eddy currents and can play an important role in various technological applications.…”

Development of high DC-bias Mn–Zn ferrite working at frequency higher than 3 MHz

“…Moreover, the prefired powder consists usually of many individual phases that react with each other to form the desired spinel phase during the final firing step [18]. In order to overcome the difficulties arising from the ceramic method and in order to prepare soft ferrites with excellent electromagnetic performance, in recent years, due to the rapid development of nanotechnology, several methods including combinatorial synthesis and high throughput screening method [19], mechanochemical processing [20,21], and numerous wet chemical methods including the coprecipitation method, the hydrothermal process, sol-gel synthesis, and the micro-emulsion approach, have been proposed to synthesize Mn-Zn ferrite nanoparticles [18, and references therein], but nanoparticles were rarely used to develop MnZn soft ferrite core further in these papers. Moreover, it is also found that the high-permeability and low power loss can be achieved using nanocrystalline ferrites in place of micro-magnetic ferrites [22].…”
