X-ray diffraction pattern of , , and ZMFO samples.
characteristic of ZMFO (a) with different electrodes (Ag, Cu, Al) at room temperature; (b) at room temperature, , and ; (c) at electric field loading rate of 0.01, 0.1, and 1 V/s; and (d) at magnetic field of 0, 0.05, and 0.1 T. Inset in (a) shows the layout of the prepared sample for measurement.
(a) Time dependence of resistance at constant voltage of 0.5, 1, 1.5, 2, and 2.5 V. (b) Pulse voltages (lower panel) and the induced resistive switching (upper panel) of the ZMFO sample at room temperature.
(a) Cole–Cole plot for complex resistivity in the sintered samples, measured at room temperature and above Tc. The inset shows the equivalent circuit for complex resistivity of samples at room temperature. (b) The nonlinear characteristics of tested samples with respect to polarity reversal of the loading voltage.
