curves of LCMO18 at the high and low current density biases. Arrow indicates position of peak in at . Inset: measured rise of sample temperature above base temperature as a function of base temperature for current .
curves obtained using low current density in and , and the curve taken with high current density in . ER as a function of temperature is shown. It may be noted that, for , while the , the MR is negligible.
characteristics in three different regimes: FMM , FMM-FMI transition region , and FMI . The inset shows a representative pulse data set in the FMI state .
Variation of power law fit parameters below and above the threshold current as a function of temperature . The sample becomes strongly nonlinear in the FMI phase.
