Abstract :
In recent decades, magnetodielectric (MD) materials have attracted a great deal of interest for both their unique physical properties as well as their potential as enabling materials in such applications as memory devices, electric field-controlled microwave resonance devices, etc. The magneto-electric effect has been observed in nature for very few single-phase materials, but many multiphase materials. These properties may arise from the interplay between granular and intergranular phases. Notwithstanding, this research may lead to many opportunities in the design of practical materials, heterostructures, and MD devices. As one of the most important microwave materials, YIG ferrite has been widely used in traditional and modern microwave devices for many decades. It is proposed that YIG ferrite with magnetoelectric or magnetodielectric effects may open a new era in the development of microwave communications by means of the electrically tunable miniature microwave devices. In the present work, we focus on the dielectric, magnetic and magnetodielectric properties of zirconium (Zr) doped Y3Fe5O12 (YIG) ferrites. This research aims to investigate the effect of Zr ion substitutions on the magnetodielectric effect of YIG ferrite materials.
