TRANSITIONS IN CHROMIUM
Abstract
The presence of a transition in pure chromium around 40C (from 25C to 65C according to the specimen investigated) was evidenced by the anomalous behavior of various physical properties in the vicinity of the transition. Four different properties - electrical resistivity, Young's modulus and Poisson's ratio, Hall coefficient, specific heat - were investigated on some of five different specimens in temperature ranges including the transition temperature. The shape and magnitude of the observed anomalies for different properties and different specimens were compared, together with the possible effect of impurities on the transition. The relationship between these anomalies and the transition from an antiferromagnetic to a paramagnetic structure was discussed in connection with neutron diffraction expe iments and anomalies in other antiferromagnetic materials.
