The ac susceptibility Χac and the dc magnetization M(H, T) of single crystals of Sm3Te4 have been measured at temperatures as low as 70 mK. A cusp is found in Χac at 1.3 K which is slightly lower than the temperature at which a broad peak of the specific heat was previously observed. Distinct irreversibility is observed in M(H, T) below ∼ 1.3 K. The results indicate that the Sm3+ moment undergoes a spin glass transition at Tg ∼ 1.3 K. It is likely that the two valence states of Sm2+(J = 0) and Sm2+(J = 5/2) are randomly frozen at low temperatures in the bcc lattice to effectively form a randomly diluted antiferromagnet.
