Abstract

We present magnetic phase diagrams to determine Néel critical field on the basis of electrical resistivity, specific heat and magnetic susceptibility measurements at magnetic fields. The magnetic phase diagrams indicate that Néel temperatures were suppressed completely at 35T for [100] and 31T for [001], respectively. These results indicate Quantum Critical Point exists in a range from 30 to 40T. This phase diagrams should be powerful guides for investigating electronic states near QCP.
