论文摘要
我们对KCR3AS3和K2CR3AS3准1D化合物进行了比较研究，并表明晶格和自由度自由度之间的强相互作用在经盘抗抗铁磁性的情况下促进了链条内的新胶线铁磁接地状态。我们建议KCR3AS3中的链链抗磁磁耦合对实验观察到的旋转玻璃相具有至关重要的作用，其临界温度较低。在参数空间的同一区域中，我们预测K2CR3AS3是非磁性的，但处于磁性的边缘，维持链链铁磁自旋波动，而内侧旋转的自旋波动是抗铁磁磁性的。
We perform a comparative study of the KCr3As3 and the K2Cr3As3 quasi 1D compounds, and show that the strong interplay between the lattice and the spin degrees of freedom promotes a new collinear ferrimagnetic ground state within the chains in presence of intrachain antiferromagnetic couplings. We propose that the interchain antiferromagnetic coupling in KCr3As3 plays a crucial role for the experimentally observed spin-glass phase with low critical temperature. In the same region of the parameter space, we predict K2Cr3As3 to be non-magnetic but on the verge of the magnetism, sustaining interchain ferromagnetic spin fluctuations while the intrachain spin fluctuations are antiferromagnetic.
