Effect of Al substitution on the magnetization reversal and complex magnetic properties of NiCr₂O₄ ceramics

Abstract

A relationship was built between the structure and magnetic properties to investigate the magnetization reversal and magnetic interaction. The result of the magnetic switching effect indicates potential applications in data storage devices.

Temperature‐induced magnetic compensation and negative magnetization in a cluster spin glass Gd2Co0.5Mn1.5O6 system

“…The negative magnetization (magnetization reversal) is an intrinsic effect in magnetic system with two or more magnetic moment vectors that have different temperature dependence 1–4 . The typical experimental character of the effect is the net magnetic moments M ↓ that is orientated along the opposite direction of a steady magnetic field H ↑ at low temperature 5,6 . This intriguing effect has aroused great interest due to its promising applications in spin switch and magnetic storage as a result of manipulation of the two distinct magnetic states 7–10 .…”

“…[1][2][3][4] The typical experimental character of the effect is the net magnetic moments M↓ that is orientated along the opposite direction of a steady magnetic field H↑ at low temperature. 5,6 This intriguing effect has aroused great interest due to its promising applications in spin switch and magnetic storage as a result of manipulation of the two distinct magnetic states. [7][8][9][10] During the formation of negative magnetization, the phenomenon of zero net moments is defined as magnetic compensation effect and its corresponding temperature is described as compensation temperature (T comp ).…”
