WebMar 15, 2007 · It can be seen that a broad stable value occurs from room temperature to around 270 °C and there is a sharp Hopkinson peak on each μi – T curve, which indicates that the samples still consist of amorphous phase. However, the room temperature μi value and the height of Hopkinson peak after annealing are higher Conclusions WebThe first peak corresponds to the compensation of magnetocrystalline anisotropy [35], whereas the second, which takes place just below the Curie point, is known as the Hopkinson peak [28]. ......
