29Si-NMR study of antiferromagnet CeRh2Si2using single crystals

29Si-NMR Study of antiferromagnet CeRh2Si2with a tetragonal ThCr2Si2-type structure has been performed using single crystals. The Knight shifts along the aand the caxes have been measured as a function of temperatures in the paramagnetic state. At ambient pressure, the Knight shifts show the Ising-type anisotropy along the caxis, which is similar to the magnetic susceptibility. The hyperfine coupling constants for 29Si along the aand the caxes have been determined from Knight shift versus static susceptibility plots.
