Abstract:	The authors investigate the magnetic and transport behaviors of Ge1-x Mnx Te thin films with high Mn composition (x=0.98) grown by solid-source molecular-beam epitaxy. The temperature-dependent magnetization (M-T) gives a Curie paramagnetic temperature θp ∼120 K, in contrast to the Curie temperature of TC ∼95 K obtained from the Arrott plot and temperature-dependent resistivity measurement. The resistivity and M-T behaviors can be attributed to weak localization effect of disordering. The authors discussed the ferromagnetism in Ge0.02 Mn0.98 Te on the basis of the Ruderman-Kittel-Kasuya-Yoshida interaction and clustering effect. © 2007 American Institute of Physics.
