Magnetic behaviour of the Cr-Al alloy system around the triple point

Proceedings of the South African Institute of Physics (SAIP) 2011. The 56th annual conference of the South African Institute of Physics,Electrical resistivity and specific heat measurements on a series of Cr1-xAlx (0 ? x ? 0.034) alloy single crystals are reported. The results indicate that the triple point, where the incommensurate and commensurate spin-density-wave phases coexist with the paramagnetic phase, is situated close to T = 0 K on the magnetic phase diagram.
