Unusual relaxational dynamics in La1 − xCaxMnO3 (x = 0.33 and 0.67)
Abstract
Muon spin relaxation studies on La1 − xCaxMnO3 (x = 0.33 and 0.67) powders show that the muon dynamic relaxation function changes from exponential above the magnetic transition temperature to stretched exponential below the critical temperature (TC = 274 K for x = 0.33, TN = 150 K for x = 0.67). This suggests a spatially inhomogeneous distribution of very slow Mn-ion correlation times. An anomalously small applied field destrroys the dynamical …
