Phys. Rev. Lett. 26, 1308–1310 (1971)Electron Critical Scattering in EuS-In Ferromagnetic Tunnel JunctionsReceived 5 April 1971; published in the issue dated 24 May 1971 We have observed a Curie-Weiss temperature dependence for electron critical scattering in In-EuS junctions which applies to within a few degrees of the ordering temperature Tc. The law holds both above and below Tc from 4.2 to 300°K. Above Tc the magnetoconductance is G(H,T)=G0(T-Tc)+G1TH2(T-Tc)-2, where G0 and G1 are constants. These results are explained by a model based on critical scattering in the mean-field limit. © 1971 The American Physical Society URL:
