Abstract
Method for obtaining a solid, magnetically anisotropic material, includes the steps of heating an alloy containing a rare earth element and at least one transition metal to a temperature higher than the melting temperature of the alloy and sufficient that alloy is completely liquid, and cooling the melted alloy at a rate at least equal to natural cooling in the presence of a continuous, static magnetic field to solidify the alloy and obtain the magnetically isotropic material.
