Melt-spun Pr2Co14B/CO nanocomposite magnets (Journal article)

Withanawasam, L./ Panagiotopoulos, I./ Hadjipanayis, G. C.

We have successfully prepared a new nanocomposite magnet consisting of a mixture of a magnetically hard Pr2Co14B phase and a soft Co phase using the technique of melt spinning. The final microstructure with the above phases is formed after annealing the melt-spun ribbons through an intermediate transformation to the metastable TbCu7-type structure. Optimum coercivity of 4.3 kOe was observed in a sample with the composition Pr8Co83Nb1B8 after heating above 775 degrees C. (C) 1996 American Institute of Physics.
