Beschreibung
Zusammenfassung:FIELD: electrical, electronic, and instrumentation engineering. SUBSTANCE: proposed material for permanent magnets is based on triple combination of iron, boron, and rare- earth metals incorporating at least one stable triple combination of Fe-B-rare-earth metal type (one or more rare-earth metals including yttrium) with tetragonal structure and nonmagnetic combinations incorporating amorphous compounds of oxide derivatives of rare-earth metals having following proportion of ingredients, mass percent: at least one stable triple combination of Fe-B-rare-earth metal type as base and amorphous compounds of rare-earth metals - 2.8-3.8. For example, triple combination may contain ingredients in following proportion, mass percent: neodymium - 2.5- 3.5; boron - 0.9-1.1; cobalt - 2.5-3.5; aluminum - 0.3-0.5; scandium - 0.01-0.05; iron - the rest. EFFECT: improved reproducibility of magnetic properties and facilitated production of material. 5 cl, 3 tbls
