MAGNETIC MATERIAL, AND ITEM MADE FROM IT Russian patent published in 2013 - IPC H01F1/57 

FIELD: metallurgy.

SUBSTANCE: proposed magnetic material includes iron (Fe), cobalt (Co), boron (B), at least one element chosen from the group of neodymium (Nd), praseodymium (Pr), at least one element chosen from the group of dysprosium (Dy), terbium (Tb), gadolinium (Gd), at least one element chosen from the group of aluminium (Al), gallium (Ga), copper (Cu); in addition, it also contains beryllium (Be), as well as at least one element chosen from the group of lanthanum (La) and holmium (Ho). With that, chemical composition corresponds to the following formula, atm %: (R¹ _1-x1-x2R² _x1R³ _x2)_13.5-15.5(Fe_1-yCo_y)_"ост".M_0.1-2.0Be_0.001-0.2B_6-9, where R¹ - at least one element chosen from group of Nd, Pr; where R - at least one element chosen from the group of Dy, Tb, Gd; where R³ - at least one element chosen from the group of La, Ho; where M - at least one element chosen from the group of Al, Ga, Cu; where x₁ - 0.05-0.50, where x₂ - 0.01-0.05; where y - 0.01-0.40.

EFFECT: possibility of increasing square-law characteristic coefficient of a demagnetising part of hysteresis loop; this considerably decreases non-convertible losses of a magnetic flux at operation of magnets being parts of magnetic devices and improves accuracy and stability of navigational equipment and systems of aviation and space automatics and navigational equipment.
