In this work, we reported the Ce-Cu co-substituted M-type strontium hexaferrites Sr0.7Ce0.3Fe12-xCuxO19 (0.00 ≤ x ≤ 0.50) prepared by using the solid-state method. The specific effect of Ce-Cu co-substitution on the magnetoplumbite structure and magnetic properties were studied systematically. The canonical M-type strontium hexagonal phase has been formed for our prepared sample in all doping range, which also has been confirmed by FTIR spectrum. In all compositional range, by the way, the magnetic competition of ferromagnetism-antiferromagnetism is reduced and gradually disappeared under the increasing substitution. Likewise, an obvious improvement of magnetic properties can be obtained; that is, Hc increases from 2850 to 3800 Oe and the value of Ms can reach up to 70.305 emu/g. The intrinsic stability and superior magnetic performance of such kind of material indicate a promising potential candidate in multilayer inductors.

Ce-Cu掺杂M型锶铁氧体对结构和磁性能的影响

在这项工作中,我们报道了Ce的铜共-取代的M型锶铁氧体的锶0.7的Ce 0.3的Fe 12- X的Cu X ø 19(0.00≤  X ≤0.50)通过固态方法制备。系统研究了铈-铜共取代对磁铅石结构和磁性能的影响。我们在所有掺杂范围内制备的样品均已形成规范的M型锶六方相,这也已通过FTIR光谱得到了证实。顺便说一下,在所有组成范围内,铁磁性-反磁性的磁性竞争都减少了,并且随着取代的增加而逐渐消失。同样,可以明显改善磁性能。即H c从2850 Oe增加到3800 Oe,M s的值最高可达70.305 emu / g。这种材料的固有稳定性和出色的磁性能表明其在多层电感器中有望成为潜在的候选者。
