摘要：

Magnetization studies were carried out on the cubic Laves phase Dy0.73Tb(0.27)Fe(2-x)Ni(x) and Ho0.85Tb0.15Fe2-yNiy [x = y = 0, 0.5, 1.0, 1.5 and 2.0] systems at 4.2 K. These studies indicate that the magnetization process is influenced by the domain wall pinning. The value of the propagation field observed increases with Ni concentration in both the systems up to x = y = 1.5 and falls to a small value for x = y = 2.0. The pinning effect is more pronounced in the case of Dy0.73Tb0.27Fe2-xNix when compared with Ho0.85Tb0.15Fe2-yNiy because of the larger K-1 value for Dy0.73Tb0.27Fe2 compared to Ho0.85Tb0.15Fe2.
