Zero‐field μ+SR study of the colossal magnetoresistance material La0.67Ca0.33MnO3
Abstract
Zero‐field μ+SR and resistivity experiments on La0.67Ca0.33MnO3 powder show that the ferromagnetic transition temperature (TC=274\ K) and resistivity peak temperature coincide to within 1 K, about 10 K higher than TC determined from the bulk magnetization. The sublattice magnetization \nu_μ(T) is well described for T ≤ TC by (1-T/TC)β , where β =0.345 ± 0.015. Unusual relaxation dynamics suggest a wide distribution of Mn‐ion correlation times. …
