Varistor‐like electrical transport is found in Nd 2/3 Sr 1/3 MnO z and Pr 0.7 Sr 0.3 MnO 3 compounds, with evidence of magnetic order–order transitions superimposed. The transition temperatures move under a magnetic field which establishes the spin‐dependent character of these phenomena. We also discuss the possibilty that the electrical field induces such transitions, as the transition appears and/or shifts at certain applied currents (or potentials).
