Spin-Freezing Process in a Spin-Glass:Cd0.6Mn0.4Te

Abstract
The time dependence of the thermoremanent magnetization has been investigated for times 102 s<~t<~102 s in Cd0.6 Mn0.4Te. The sudden appearance of a slow relaxation regime at temperature Tf0=13.10±0.03 K, superimposed on a much faster regime varying continuously through Tf0, supports the phase-transition hypothesis.
