Abstract
The concentration dependence of the Neel temperature for the dilute Cr-Ga alloy system has been determined by measuring the electrical resistivity and thermal expansivity. By addition of Ga, the Neel temperature decreases at first and then increases abruptly, showing a minimum around 0.7% Ga. This behaviour is very similar to that of the dilute Cr-Al alloy system. The antiferromagnetic spin structure has been presumed to be incommensurate with the lattice below 0.7% Ga from the results of concentration dependence of the Neel temperature and thermal expansion characteristics.Keywords
