Abstract

The critical magnetic properties of bulk La0.67Ca0.33MnO3 and magnetoresistance of a thin film with the same Tc were measured and critical exponents determined. The magnetization data can be scaled with β = 0.3 and γ = 0.9, except above Tc which appears to be affected by a region where χ3 (M = χH+χ3H3) is positive. An M2 dependence of the magnetoconductivity is observed above Tc. Below Tc, however, such a correspondence between the critical magnetic and transport behavior is not found.
