摘要：

The Gd-based pyrochlore Gd2Sn2O7 is an easy-planar anisotropic system. The CF anisotropy has a significant effect on the magnetic specific heat C-mag of this compound in the low temperature magnetic ordering regime. The C-mag is found to drop exponentially with C-mag proportional to 1/T-2 exp (-Delta(1)/T) between 0.12 and 0.31 K with anisotropic energy gap Delta(1) approximate to 1.3 +/- 0.01 K induced by single-ion CF anisotropy.
