Abstract
This invention relates to an alloy suitable for the production of permanent magnets and based on a cobalt/rare earth metal alloy in the atomic ratio of 5:1 to 7:2, where the rare earth metal component is composed of about 40 to 60 atomic percent of samarium, about 15 to 30 atomic percent of lanthanum, about 15 to 30 atomic percent of neodymium, and the remainder is a content of other rare earth metals resulting from preparation.
