Abstract

Experimental manifestations of current enforced metastable conductivity in La 0.82Ca 0.18MnO 3 single crystals are discussed. Metastable conductivity manifests itself by complex current dependence, a pronounced bias dependent structure, resistance hysteresis, enhanced noise with non-Gaussian components, and long relaxation times. Spin polarized tunneling through intrinsic tunnel junctions associated with a network of twin boundaries has been tentatively associated with the phenomena observed.
