Critical behavior study around the ferromagnetic phase transition in Pr2Pt2In

The magnetic ordering in Pr 2 Pt 2 In was investigated by means of magnetization and magnetic susceptibility measurements. The compound was found to order ferromagnetically at T C = 8.8(2) K with a second-order phase transition. The derived critical exponents β = 0.325(2), γ = 1.058(2) and δ = 4.26(4) are close to those expected for a 3D Ising ferromagnet.
