摘要： Magnetic powder of the samarium/praseodymium/cobalt type and of the samarium/praseodymium/neodymium/cobalt type having specific compositions is substantially composed of (1-5) single phase, has improved residual magnetic flux density and a high maximum energy product, and is hence suitable for resin magnets. In addition, production cost is lower compared with conventional rare-earth metal/cobalt type magnet powder because part of samarium metal has been replaced by praseodymium and neodymium which are more abundant and less expensive materials.

摘要： The magnetic properties of a thin strip of amorphous alloy are improved by imparting external stress such as tensile force and compressive force as by means of rollers to the surfaces of the thin strip of alloy while keeping the thin strip heated at a temperature which does not impair the mechanical properties of the amorphous alloy, thereby eliminating the internal stress of the alloy which tends to impair the magnetic properties.
