摘要：

The polycrystalline Sm1-xNdxFe1.93 (x = 0, 0.08, 0.12, 0.16, 0.2, 0.24, 0.32, and 0.36 ) compounds are found to stabilize in MgCu2-type C15 cubic Laves phase structure. The compound x = 0.12 is found to exhibit giant magnetostriction value of -1572 x 10(-6) due to the anisotropy compensation between Sm3+ and Nd3+ ions. The easy direction of magnetization (EMD) is observed towards [111] for the 0 <= x <= 0.20 compounds, accompanied by a rhombohedral distortion. For the x = 0.32 compound, an orthorhombic distortion, with a support that the EMD is towards [110], is observed. (c) 2007 American Institute of Physics.
