MAGNETIC MATERIAL AND PRODUCT THEREOF Russian patent published in 2005 - IPC

Abstract RU 2244360 C1

FIELD: powder metallurgy.

SUBSTANCE: invention provides magnetic material expressed by following empiric formula: (Pr_1-x1-x2R1x1

R2x2

)_14-20(Fe_1-y1Co_y1)_restB_4-10, where R¹ is at least one element selected from the group consisting of Tb, Dy, Ho, Er. Tm; R² is at least one element selected from the group consisting of Sm, La, Ce, Nd, Y; xq = 0.2-0.5; y1=0.2-0.3; x1/x2 ≥5. Material may further contain at least one element selected from the group consisting of Al, Ga, Ti, Nb, Mo, Cu. Such composition enhances magnetic properties and simultaneously temperature stability of material is increased.

EFFECT: increased accuracy and stability of operation of navigation equipment and aircraft automatic system.
