Magnetic moment and curie temperature of amorphous (Fe100-xBx)88Nd12±e alloys

The magnetization curves at 1.5K and Curie temperature of amorphous (Fe100-xBx)88Nd12?e alloys were measured. Their spontaneous magnetizations is explained by a noncollinear structure. The average magnetic moment vin-?Fe per Fe atom decreases monotonically with increasing x, and becomes more rapid when x?>?24. The B content dependence of Curie temperature shows a maximum at x?=?15. At x?exchange interactions between Fe-Fe atoms.
