Abstract
Electrical resistivity of La1−x Sr x CoO3 is reduced significantly by the substitution of Ni3+ ions in place of the cobalt ions. In the La1−x Sr x Co1−y Ni y O3 system, for small values ofx(x=0·05) superparamagnetic clusters seem to be formed at lower temperatures (<300 K). The formation of such clusters is not affected by the presence of nickel ions. Whenx is large, the occurrence of long-range ordering seems to depend on the itinerancy of charge carriers.
