ABSTRACT:
A method of converting magnetic energy to mechanical energy comprising subjecting a material of the formula R.sub.x T.sub.1-x wherein R is a rare earth or mixtures thereof, T is Fe, Ni, Co, Mn, or mixtures thereof, and 0<x<1, to a change in magnetic field and of converting mechanical energy to magnetic energy comprising subjecting a material of the formula R.sub.x T.sub.1-x to a change in pressure.
