Ce3Pt4 : A local moment antiferromagnet with two metamagnetic transitions

Abstract In this paper we present the data of the magnetic susceptibility and the low temperature specific heat of Ce 3 Pt 4 . The large anomaly in the specific heat and the behaviour of the magnetic susceptibility are explained by an antiferromagnetic phase transition at T N =2.8 K. The entropy due to the phase transition is Rln2 per mole Cerium indicating a local moment antiferromagnet.
