Electrical resistivity of compounds with ordered Spin arrangements

Abstract

A summary is given of the published data of electrical resistivity of semiconductors which exhibit ordered spin arrangements below a Curie or Néol temperature. It is found generally that electrical anomalies accompany the advent of magnetic order only if the specific resistivity at the transformation temperature is less than a critical value. The implications of this rule discussed in the light of recent theories of electrical conduction in spontaneously magnetized materials.
