High Field Metamagnetism of PrRh2Si2 Single Crystal Compound Having Anomalously High Nèel Temperature

High field magnetization up to 18 T and magnetic susceptibility measurements have been carried out on a PrRh2Si2 single crystal. The anomalously high Neel temperature of 70 K is confirmed. A strong uniaxial magnetic anisotropy with the easy c-axis is evidenced. A sharp metamagnetic transition appears at 16 T in the easy c-axis magnetization process while magnetization in the basal plane is very small and the curve is linear. The saturation moment obtained is 3.1μB. Crystalline electric field (CEF) effects have been analyzed to discuss the magnetic behaviors.
