- 論文の詳細を見る
We report the magnetic properties of pyrochlore rare earth oxides R_2Sn_2O_7 (R=Pr, Nd, Gd, Tb, Dy, Ho, Er, Tm and Yb). The magnetic susceptibility has been measured at temperatures down to 0.1 K. Among them, some compounds show the magnetic anomaly below 1 K. Nd_2Sn_2O_7 and Gd_2Sn_2O_7 show an antiferromagnetic ordering at 0.9 K and 1.0K, respectively. Tb_2Sn_2O_7 shows a ferromagnetic ordering at 0.87 K. Although both Er^<3+> and Yb^<3+> are a Kramers ion, no magnetic anomaly is observed at least down to 0.15K. We found that Dy_2Sn_2O_7 and Ho_2Sn_2O_7 show `spin ice' behavior. In addition, it is suggested that Pr_2Sn_2O_7 is a new spin ice compound.
