| 中文摘要 | Single crystal of a new layered manganese selenide KMnAgSe2 was grown by the self-flux method. It adopts a ThCr2Si2-type structure and is isostructural to KMnCuSe2, with Mn and Ag being randomly distributed at the tetrahedral sites formed by Se. The metal-metal distance within the MnAgSe2 layer is much longer than that in KMnCuSe2, resulting in a significant increase in resistivity, with an optical band gap up to 2.02 eV. The observation of spin-glass behavior in KMnAgSe2 and the strong anisotropic expansion of its lattice parameters point out that short metal-metal distance is not necessary for the induction of spin-glass behavior. Rather, magnetic anisotropy measurement on KMnAgSe2 single crystal suggests that the interlayer magnetic interaction is a more critical factor. |
