MAGNETIC MATERIAL Russian patent published in 1999 - IPC

FIELD: powder metallurgy, in particular, materials with specific physical characteristics. SUBSTANCE: magnetic material contains Fe-B-Co-R, where R is sum of rare-earth elements. Composition conforms to formulation , where R is at least one element from group of dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), and x₁+x₂-0,1-0,99,x₁/x₂≥0,10,Y₁-0,2-0,5. In addition magnetic material contains at least one element from group of aluminum (Al), gallium (Ga), titan (Ti), niobium (Nb), molybdenum (Mo). Chemical composition conforms to formulation , where T is at least one element from group of aluminum (Al), gallium (Ga), titan (Ti), niobium (Nb), molybdenum (Mo), Y₂ is in range of 0.01-10 % of atomic weight. EFFECT: increased temperature stability, temperature inductance rate is in range of +0.05 to -0.08%/C in temperature range from -60 to +150 C. 2 cl, 2 dwg, 3 ex
