Investigation of the magnetic properties of homogeneous copper-manganese alloys

The magnetic characteristics of homogeneous copper—manganese alloys Cu1 − xMnx are studied by the muon spin relaxation technique for the first time. It is revealed that the specific magnetic phase, which is most likely characterized by a fast spin dynamics and the absence of long-range order, is formed in alloys with concentrations 0.2 < x < 0.7 in the temperature range 10–330 K. The complete magnetic phase diagram is constructed.
