| Research Abstract |
It was theoretically and experimentally found that the susceptibility and magenetostriction become maxima on a magnetic easy axis boundary(MEAB) in the mixture alloy of two ferromagnetic materials with different magnetic easy axes. The super magnetostriction is observed under certain conditions, when one or the other of two shear elastic stiffness constants, C_<44> and C'(=(C_<11>-C_<12>)/2), is softened. The super magnetostriction of rare earth. iron Laves phase alloy on MEAB is the former case and that of Ni_2MnGa around T_2 the latter.
