Current oscillation and low-field colossal magnetoresistance effect in phase-separated manganites

M. Tokunaga, H. Song, Y. Tokunaga +1

Current-induced switching from metallic to insulating state is observed in phase-separated states of (La_{1-y}Pr_y)_{0.7}Ca_{0.3}MnO_3 (y=0.7) and Nd_{0.5}Ca_{0.5}Mn_{1-z}Cr_zO_3 (…
