Abstract

A method of producing a body that has permanent, anisotropic magnetic properties, the essential component for said properties being a compound that has a hexagonal crystalline structure whose existence margin forms a set with the existence margin of the M5R compound that appears in the M system. - R, where M is Co or a combination of Co with one or more of the elements Fe, Ni and Cu, and where R is one or more of the rare earth elements and/or Th, by sintering of a powder consisting of a compound of M and R, characterized in that first castings are produced, having at least one atomic proportion (see formula) and having another an atomic proportion (see formula), which are pulverized and mixed in an atmosphere that protects against oxidation and that contains less than 100 p.p.m. oxygen and/or water vapor, because in the same atmosphere said powder is then oriented in a magnetic field, compressed and sintered between 800ºC and 1250ºC.
