چکیده انگلیسی
Mn1.95Cu0.05SbBx (x = 0, 0.06 and 0.1) alloys had been prepared and B interstitial effects on metamagnetic transition were studied. The metamagnetic transition temperature was reduced and thermal hysteresis was widened by higher B concentration. The saturation magnetization and the magnetic entropy change were increased by moderate amount of B addition. However, too high B composition led into the sluggish metamagnetic transition. By relating with crystallographic structure, our results further indicated that the electron density of the atoms at Mnâ
¡ position plays critical role on influencing the metamagnetic transition in tetragonal Cu2Sb-type Mn1.95Cu0.05Sb alloys.
