Description
The effect of the substitution of Mn with In in the magnetoresistive La2/3Ca1/3MnO3 compound has been studied by means of X-ray diffraction, a.c. magnetic susceptibility, d.c. magnetization, and d.c. resistance techniques. This substitution is possible for x ≤ 0.07 under normal synthetic procedures. The Curie temperature decreases with increasing x in La2/3Ca1/3Mn1-xInxO3. Samples with x ≥ 0.05 do not show long-range ferromagnetic order but rather a cluster-glass behavior. Magnetic inhomogeneities, arising both from random substitution of Mn with In and from formation of oxygen vacancies, can lead to such behavior. Samples with x ≥ 0.05 do not show metal-insulator transition
