J. Stankiewicz et al., Magnetic behavior of Pr1-xCaxMnO3 in the electric-field-driven insulator-metal transition, PHYS REV B, 61(17), 2000, pp. 11236-11239
The magnetization through an electric-held-driven transition from a charge
ordered state to a conducting one in polycrystalline Pr1-xCaxMnO3, with x =
1/3 and 0.4, have been measured, simultaneously with current-voltage chara
cteristics. These measurements have been performed at several temperatures
and magnetic fields in the ranges 20-40 K and 0-3.5 T, respectively. A sign
ificant increase in the magnetization, observed at the transition, fits in
with a two phase model of insulator-metal transition in this system.
