Temperature dependence of the resistivity of BSMO for dc current values of and 20 mA. The -axis shows the base temperature of the sample measured by the cernox sensor installed in the cryostat close to the sample holder. The -axis on the right scale shows the temperature measured by the Pt-sensor glued on the top surface of the sample.
The dc and pulsed (a) current density dependence of the dc electric field and (b) the electric field dependence of the current density at .
(a) Resistivity switching at triggered by changes in pulse widths under different periods: (a) , (b) , and (c) trilevel resistivity switching for three different pulse widths for . The numbers in the graphs indicate pulse widths.
