Abstract
Magnetic susceptibility, magnetization and specific heat measurements have been performed on single crystalline Ce(Ru 1- x Rh x ) 2 Si 2 in the Ru rich region(0≤ x T K , the antiferromagnetic (AF) correlation and the metamagnetic transition in CeRu 2 Si 2 . Phase diagrams are obtained in both x - T and H - T planes with fields applied parallel to the tetragonal c -axis. At low Rh concentration, T K decreases with x and a weak AF ordering ( T N ≤5.5 K) appears in the region 0.05< x H M decreases with x , leveling off and disappearing above x =0.20. This metamagnetic transition clearly exists in the AF ordered samples, where two successive transitions are observed in fields at H C (5 T). The AF ordering is destroyed above H C and the system further undergoes a metamagnetic transition at H M .Keywords
