Abstract

The high performance internal-temperature-compensated 2:17 type SmCo sintered magnet with composition of Sm_0.56Gd_0.3Dy_0.14(TM)_7.22 (TM = Co_0.68Fe_0.22Cu_0.08Zr_0.02) was successfully prepared. The optimum magnetic and temperature properties are: B_r = 8800 Gs, _bH_c = 8200 Oe, (BH)_max = 18 MG Oe^-1, α_20-100°C = -7 X 10^-6/°C. It was found that the domain wall pinning in Gd compensated magnets is more predominant than that in Dy compensated magnets.
