Multifunctional behavior of solid-state derived Ca-doped BaFe0.5Nb0.5O3 complex perovskite system

Investigation of the structural, dielectric, magnetic properties and NTC-thermistor response of CaBiFeMnO6 double perovskites

“…Here, eqn ( 15) and ( 16) are the Akulov and Ne ´el approximations, respectively, for LAS. 73 From the fitted graph, it is evident that the experimental data does not follow Brown's approximation, but the other two approximations are approaching a saturation value at a certain magnetic field.…”

“…The magnetocrystalline anisotropy from hysteresis loops is obtained by applying the law of approach to saturation (LAS). 73 The variance of M – H in the higher field domain is explained by the law of approach to saturation (LAS), which can be illustrated by the following equation.…”
