Abstract

The authors find that for mechanically milled Ni0.5Zn 0.5Fe2O4 (∼ 10 nm), the mechanical strain induced enhancement of anisotropy energy helps to retain stable magnetic order. The reduction of magnetization can be prevented by keeping the cation distribution of nanometric ferrites at its equilibrium ratio. Moreover, the sample can be used in coding, storing, and retrieving of binary bit ("0" and "1") through magnetic field change.
