Varistor-like electrical transport is found in magnetically ordered Nd 2/3 Sr 1/3 MnO 3− δ compounds for δ >0.05. However, because of correlations of characteristic structures with the magnetic behaviour, transport through magnetic grain or phase

Spin-dependent varistor-like electrical transport is found in Nd 2/3 Sr 1/3 MnO 3- δ compounds for δ ⩾0.1, for which the transport through magnetic grain or phase boundaries is responsible. Specifically, electrical-field-induced changes of the sp
