Abstract

The magnetic Compton scattering technique is employed to analyze the first and second order magnetic transitions taking place in the Ir doped Ce[F.sub.2] compound. The spin-polarized momentum densities of the system are shown to be highly temperature and field dependent.

89. Variation of magnetoresistance in [Ni.sub.2+x][Mn.sub.1-x]Ga with composition

Abstract

A large increase in magnitude at room temperature (RT) with increasing x, exhibited by the magnetoresistance (MR) of [Ni.sub.2+x][Mn.sub.1-x]Ga ferromagnetic shape memory alloy which could be varied over one order of magnitude by changing composition (x) is reported. Compared to the monotonic MR variation with x, the magnetization at RT is found to be highest for [Ni.sub.2]MnGa (x=0) and decreased for both Ni and Mn excess compositions.
