Fig. 4.
Longitudinal and transversal resistivities. a Longitudinal resistivity (DC probing current density 104 A/cm2) vs. number of applied pulse trains. The inset shows the longitinal resisitvity of another sample. In this case saturation of the magnetoresistance could be obtained for a few repetitions before the sample broke. b Transversal resistivity of the same sample as shown in the main panel of a vs. number of applied pulse trains. The crystallographic direction in which the current pulses were injected is indicated by the cyan and red color of the data points
