We present realistic Kondo-lattice simulation results for the recently discovered heavy-fermion antiferromagnet CePt2In7 comparing with its three-dimensional counterpart CeIn3 and the less two-dimensional ones, Ce-115’s. We find that the distance to the magnetic quantum critical point is the largest for CeIn3 and the smallest for Ce-115’s, and CePt2In7 falls in between. We argue that the trend in quasi two-dimensional materials stems from the frequency dependence of the hybridization between cerium 4f electrons and the conduction bands.
