Abstract

Measurements and analysis of the paramagnetic susceptibility of La1-xCaxMnO3+y (0 ≤ x ≤ 1) are reported. The magnetization was also measured in large fields (H ≤ 18 tesla) for a specimen of La0.79Ca0.21MnO3+y. The paramagnetic susceptibility is observed to be strongly enhanced for most compositions studied, including a number of antiferromagnetic compositions. This behavior is attributed to the existence of magnetic polarons.
