我们研究磁各向异性(MA)的Y型铁氧体使用电子理论在0 K,以前适用于M型和尖晶石铁氧体。在计算中,我们考虑了铁氧体(M2Y铁氧体)中M2+离子周围的局域晶格结构,其中M代表Fe,Co,Ni和Cu。通过确定M2+可能的占据位置,将计算出的MA能量(磁化强度Ms平行于和垂直于六方晶格c轴的状态的磁能之差)与实验值进行了比较。Co 2 Y和Ni 2 Y的MA能量分别为− 0.33和− 0.39 MJ m− 3。负号表示Ms在晶格的c平面内。详细分析了M2+周围的局域晶格结构对M2 Y铁氧体磁匹配的影响。计算了Co2Y的c面MA常数K3,并与实验值进行了比较。此外,还对Mg2Y和Zn2Y的MA进行了研究.本研究之结果将有助于设计适用于超高频之Y型铁氧体。
We study magnetic anisotropy (MA) of the Y-type ferrites using an electron theory at 0 K that was previously applied to M-type and spinel ferrites. In our calculation, we consider the local lattice structure around M 2+ ions in the ferrites (M 2 Y ferrites), where M represents Fe, Co, Ni and Cu. The calculated MA energy, difference between magnetic energies of states with magnetisation M s parallel and perpendicular to c-axis of the hexagonal lattice, is compared with the experimental values by identifying possible occupation sites of M 2+. The calculated MA energies of Co 2 Y and Ni 2 Y are− 0.33 and− 0.39 MJ m− 3, respectively. The negative sign indicates that M s is within the c-plane of the lattice. We have analyzed in detail how the local lattice structure around M 2+ affects the MA of the M 2 Y ferrites. The c-plane MA constant K 3 of Co 2 Y is also calculated and compared with the experimental value. In addition, the MAs of Mg 2 Y and Zn 2 Y are examined. The findings of this study may contribute to design Y-type ferrites which are applicable to hyper-frequency regime.
