Abstract

Measurements of muon spin relaxation have been performed on Ce ₂RhIn_8-xSn_x (x = 0.0,0.1,0.5 and 0.7) single crystals down to 0.3 K. A clear muon spin precession signal was observed in x = 0.0 and 0.1 samples due to antiferromagnetic ordering with magnetic volume fraction of ∼75% below T_N. While an increase of relaxation rate was observed in x = 0.5 below 0.5 K, no precession signal was observed, suggesting the suppression of antiferromagnetism with increasing Sn concentration.
