  • Method for preparing a rare earth- and transition metal-based magnetically anisotropic material by solidifying a liquid alloy in a guiding field
    Patent number: 6210495
    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.
