Critical exponents and amplitude ratios from electrical resistivity measurements of dysprosium
Resistive anomalies in helical antiferromagnets are shown to reflect the temperature dependence of the specific heat sufficiently close to the Neel temperature. The temperature dependence of superzone energy gaps does not ... -
Resistive anomalies at the critical point of isotropic ferromagnets
The effect of spin fluctuations on electrical resistivity (T) is studied in a single-band model. It is shown that d(T)/dT varies as the magnetic specific heat for TTc as well as TTc and that both short-range and long-range ...
