|Abstract:||We show that magnetic field (H) dependence of resistivity (ρ) in Nd0.5Ca0.5Mn0.95Ni0.05O3 shows unusual features with increasing amplitude of the dc current (I) in the sample. While ρ (H) at T = 40 K decreases smoothly with increasing H and exhibits irreversibility with field cycling for current amplitudes less than 1 mA, an avalanche like decrease occurs at a critical value of H for I > 5 mA. The critical field increases with increasing amplitude of the dc current and the ρ (H) exhibits a reversible hysteresis in the complete field cycle at higher dc current strengths. It is shown that the avalanche in ρ is accompanied by an abrupt decrease in the temperature of the sample (Δ T = 47 K) which underscores the importance of magnetothermal coupling in the current-induced magnetoresistance avalanche. © 2010 Elsevier Ltd.
