我们报道在重费米子反铁磁体Ce_2RhIn_8中发现了压力诱导超导性,T_c= 2k,其中超导性和磁序在延长的压力区间内共存。正常状态下的t -线性电阻率,在外加磁场作用下,似乎并不源于二维量子临界自旋密度波的存在。
We report the discovery of pressure-induced superconductivity, with T_c=2 K, in the heavy-fermion antiferromagnet Ce_2RhIn_8, where superconductivity and magnetic order coexist over an extended pressure interval. A T-linear resistivity in the normal state, accessed by an applied magnetic field, does not appear to derive from the existence of a 2D quantum-critical spin-density wave.
