Abstract
Hard direction magnetization recoil curves were analysed taking into account the angular distribution of grain axes for textured (x = 0 and 1) samples. Magnetocrystalline anisotropy constants and were determined in the temperature range between 1.5 K and 300 K using the textured samples. The anisotropy field was examined by the singular point detection technique results at room temperature. A maximum value of intrinsic coercivity around 1.02 T and 1.24 T at room temperature was obtained for x = 0 and 1 ribbons, respectively. The mechanism of coercivity was mainly controlled by the nucleation of reversed domains. The micro-structural parameter and the averaged local effective demagnetization factor were derived from the temperature dependence of the coercivity.
