Magnetocrystalline anisotropy in the Co/Fe codoped Aurivillius oxide with different perovskite layer number

Perpendicular magnetic anisotropic materials are of great interest for their huge potential to realize high‐density nonvolatile memory and logic chips. Designing such materials with lower cost and better magnetoelectric coupling still remains major challenges. In this work, aurivillius oxide ceramics with highly [ 00l ]‐oriented grains were prepared by a facile pressureless sintering method, and the perovskite layer number was modified by...
