The effect of applied pressure up to 13 kbar on the magnetic properties of Mn0.615Cr0.385As has been studied by powder neutron diffraction. Because of a slightly uneven distribution of Mn and Cr in the metal sublattice two helimagnetic (Ha and Hc types phases coexist at ambient pressure and 80 K. On subjecting the sample to external pressure, the Ha type mode is converted into a ferromagnetic (F) mode. The results agree with the findings for the analogous phase Mn0.64Cr0.36As1−xPx, where the lattice is exposed to internal, chemically induced pressure.
