Abstract

The magnetic susceptibility of Te, MnTe2, and three dilute TeMn alloys was measured from room temperature to 800°C. The effective magnetic moment of dilute Mn in liquid Te is 5.0(2) μB and appears to be slightly temperature dependent. The effective moment for Mn in MnTe2 is 6.05 μB, approximately equal to that of a free 5/2 spin. The Weiss temperature of MnTe2 is 610(20) K. These data are used to determine an accurate phase diagram for Terich Mnx Te1−x. The eutectic is found at 0.6(1) at. % Mn with a eutectic temperature within 2°C of the tellurium melting temperature. Because liquid tellurium remains in metastable equilibrium with solid MnTe2 as much as 80°C below the eutectic, a metastable lowtemperature extension of the liquidus is also determined.
