Abstract
We present measurements of the magnetic and structural properties of the magnetic semiconductor MnIn2Se4 and Zn 1-xMnxIn2Se4(x = 0.87). The localized Mn ions in the layered rhombohedral structure undergo a spin-freezing transition below 3.5 K. The frequency-dependent freezing temperature T f varies as ΔTf/(TfΔlogω) ≈0.022, indicating spin-glass behavior. © 2003 Elsevier B.V. All rights reserved.
