Spin glass behavior of Cd1−xMnxTe below the nearest-neighbor percolation limit

Abstract
Magnetization measurements down to 10 mK of Cd1−xMnxTe for Mn concentrations 0.01≤x≤0.15 show spin glass behavior. Such behavior is attibuted to short‐range exchange and dipolar interactions. Both interactions are used to explain the concentration dependence of the spin freezing temperatures for 0.01≤x≤0.6, the short‐range exchange dominating at high concentrations, and the dipolar interaction at low concentrations.
