摘要：
The magnetic properties of polycrystalline PrRh2Si2 sample have been investigated by neutron diffraction measurements. Antiferromagnetic transition with an anomalously high ordering temperature (T-N similar to 68 K) is clearly observed in magnetic susceptibility, specific heat, electrical resistivity and neutron diffraction measurements. Neutron diffraction study shows that Pr3+ ions carry an ordered moment of 2.99(7)mu B/Pr3+ and align along the crystallographic +/- c-directions for the ions located at the (0,0,0) and (1/2; 1/2; 1/2) positions. The magnetoresistance at 2 K and 10 T is rather large (similar to 35%). (C) 2008 Elsevier B.V. All rights reserved.
