Abstract: | The magnetic properties of polycrystalline PrRh2Si2 sample have been investigated by neutron diffraction measurements. Antiferromagnetic transition with an anomalously high ordering temperature (TN∼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)μB/Pr3+ and align along the crystallographic±c-directions for the ions located at the (0,0,0) and positions. The magnetoresistance at 2 K and 10 T is rather large (∼35%). |
