Abstract
The pressure phase diagrams for Mn1-tCrtAs with t = 0.355 and 0.390 were determined. The observed topology around the two types of heli-ferro-para triple points may indicate multicritical behaviour. The value of dTC/dP = +11 K/kbar for the induced ferromagnetic phase (t = 0.390) represents the highest positive pressure slope observed for a metallic magnet.
