Collapse of ferromagnetism in amorphous (Fe0.65Mn0.35)75 P16B6Al3

Abstract
We present low-field dc-magnetization measurements on (Fe0.65Mn0.35)75 P16 B6 Al3 ribbons and show that in this system there exist two phase transitions, such that the spontaneous magnetization goes to zero at Tc and Tf+, while the low-field susceptibility diverges at Tc+ and Tf.
