Abstract
Intrinsic magnetic properties of (Fe1-xCox)2B (x = 0.20, 0.25, 0.30, 0.35) alloys have been studied on single crystals. Temperature dependence of both magnetocrystalline anisotropy constant K1 and spontaneous magnetization Ms has been determined from magnetization isotherms measured between 10 and 1000 K. The highest anisotropy constant K1 was obtained at x = 0.25, K1 = 494 kJ/m3 at T = 10 K. The Curie temperature decreased from 966 to 930 K as x increased from 0.2 to 0.35.
