We report on the magnetic measurements of the semimagnetic semiconductor Zn0.15Mn0.85Ga2Se4(ZMGSe). The DC susceptibility and high magnetic field indicate that the ZMGSe orders antiferromagnetically at T≈6 K and undergoes into a spin-flop phase below this temperature. Arrott plots and magnetic entropy changes were used to characterize the order of the transitions. © 2006 Elsevier B.V. All rights reserved.
