Firstly, the incommensurate magnetic scattering of the doped single-layer triangular lattice in the normal state has been studied. It is shown that away from half-filling the commensurate peak is replaced by six incommensurate peaks located at [ (1-δ〓), ] , [ (1-δ′〓), ] , [ (1-δ"〓), ] , respectively, and 〓〓. The incommensurability parameter δ increases with doping at lower doping concentration, while saturates at higher dopings. These peaks broaden and weaken in amplitude with increasing energy and temperature, with the positions of the incommensurate peaks not changing with the energy.

利用t-J模型，讨论了单层和双层三角晶格材料的非公度磁散射，结果表明：随着掺杂的增加，三角晶格反铁磁体出现公度-非公度转变，即由一个公度峰变为六个非公度峰，并且非公度率在较低掺杂时随着掺杂浓度的增大而增大，在较高掺杂浓度时将达到饱和；虽然非公度峰的权重随着能量的增大而减小，但非公度峰的位置与能量无关，即非公度率是不随能量变化的，并且我们还发现非公度峰的权重随着温度的升高也是减小的。
