Descripción
DC electrical current-dependent resistance and pulsed current-voltage characteristics as a function of temperature of mixed valent Mn oxide-based La5/8-yPryCa0.375MnO3 (y = 0.35) single crystals are reported. We find that the low-temperature regime of this material is strongly current dependent. For small current densities (∼ 10μA/cm2), the metal-insulator transition related to the low-temperature enlargement of the ferromagnetic fraction is not observed down to 10K. Higher current densities causes a large decrease of the resistance, which is temperature dependent and exhibits memory effects. Our results are interpreted within a scenario of strong competition between charge and ferromagnetic ordering. © 2004 Published by Elsevier B.V.
