Abstract

The dependence of GMR properties on the magnetic (partially filled d-shell) and non-magnetic (closed d-shell) dopant elements in La0.7Ca0.3MnO3 and Pr0.7Ca0.3MnO3 has been studied. It is found that non-magnetic element substitution drastically affects the ferromagnetic transition temperature.
