摘要:

CePt $_2$ In $_7$是一种新的重费米子体系,其结构类似于CeMIn $_5$体系,但具有更强的二维性质。本文报道了纯相多晶材料的合成和表征,该材料在$T_N = 5.2$ K处发生反铁磁转变。核四极共振(NQR)研究表明,反铁磁性是相称的,并表现出强的反铁磁性涨落顺磁状态。

英文摘要:

CePt$_2$In$_7$ is a new heavy fermion system with a structure similar to the CeMIn$_5$ system but with greater two-dimensional character. We report the synthesis and characterization of phase pure polycrystalline material, which reveals an antiferromagnetic transition at $T_N = 5.2$ K. Nuclear Quadrupolar Resonance (NQR) studies indicate that the antiferromagnetism is commensurate and exhibits strong antiferromagnetic fluctuations in the paramagnetic state.
