为了阐明稀释伊辛磁体在整个磁浓度范围内的磁激发，我们对二维稀释伊辛磁体 Rb 2 Co c Mg 1− c F 4,(c= 0.1, 0.2, 0.3, 0.4, 0.5, 0.58) 进行了中子非弹性散射实验，其磁浓度低于逾渗阈值。我们发现伊辛团簇激发和团簇内激发在整个浓度区域中共存，并且来自这些不同来源的散射强度随着浓度的变化而变化。
To elucidate magnetic excitations in diluted Ising magnets over the entire magnetic concentration, we performed neutron inelastic-scattering experiments on two-dimensional diluted Ising magnets Rb 2 Co c Mg 1− c F 4,(c= 0.1, 0.2, 0.3, 0.4, 0.5, 0.58), whose magnetic concentration was below the percolation threshold. We found that Ising cluster excitations and intracluster excitations coexist over the entire concentration region, and that the scattering intensities from these different origins change with the concentration.
