Abstract

Procedure for preparing permanent magnetic materials containing rare earths, which can be represented by the approximate formula mx-ym'and re in which m is at least one of the elements selected from the group consisting of cobalt and iron, m' is, at least one of the elements chosen from the group consisting of copper, nickel and aluminum, re is at least one of the elements selected from the group comprising samarium, cerium, gadolinium, praseodymium, lanthanum, yttrium, neodymium and holmium, x is from about 5 to about 8.5 ey is the atomic fraction from 0.02x to 0.98x, the steps of mixing the indicated ingredients to produce said composition, forming the mixture in a body in a convenient manner, heating the body thus formed and thermally treated the heated body, characterized by carrying out said thermal treatment at a temperature that falls within the range of from a temperature of about 5ºC below the melting point of the composition to 800ºC for a period of from 1 minute to 1,000 minutes, and by cooling the heat treated body at a rate of from 100ºC per second to 0.01ºC per second over the range of heat treatment temperature to at least 500º c.
