Activated Dynamic Scaling and Magnetic Ordering in Cd sub (1-x) Mn sub (x) Te: Spin Glass or Random Antiferromagnet?
The dynamics of magnetic fluctuations have been investigated in the frustrated and random antiferromagnet Cd sub (1-x) Mn sub (x) Te. The frequency dependent susceptibility X'(w,T) has been measured by Faraday rotation for x -.4 and x=.65.
