The magnetic phase diagram of a dilute Cr---Ga system

The boundaries of the magnetic phase diagram of a dilute Cr---Ga system have been determined from measurements of the temperature and pressure dependence of the electrical resistivity. The phase boundaries separating the observed magnetic states, namely the paramagnetic state and the incommensurate and the commensurate spin density wave states, meet at about 0.5 at.% Ga, the triple point for this system.
