Abstract

Amorphous melt-spun Pr2(Fe1-xCox) 14B has been prepared to test the concept of magnetic-field-induced crystallite alignment. Crystallization temperatures (Tx) of alloys with x=0.5, 0.6, and 1.0 were determined to be 622, 646, and 507°C, respectively. These temperatures are all lower than the Curie temperatures (Tc) of the crystallized 2:14:1 phase. The glasses were then heat treated at a temperature Tt(Tx<Tt<T c), either in no field or in a magnetic field of 0.3 T applied parallel to the long edge of the ribbon. The degree of alignment was investigated by means of x-ray diffraction and magnetization measurements. A texture was found where the c axes tend to lie in the ribbon plane in zero field, which is slightly modified when a magnetic field is applied during the heat treatment.
