Spin-PeierlsWe investigate the role of the spin–lattice coupling in the antiferromagnetic molecular rings and the possible appearance of a dimerized phase. We argue that the Cu 8 might be a good candidate to observe such a phase.doi:10.1016/j.jmmm.2003.12.633L. Spanu...
We suggest that the lattice distortion caused by the Li-doping is responsible for the enhancement of the phase transition. 展开 关键词:Vortex Magnetism DOI: 10.1209/0295-5075/94/37003 被引量: 2 年份: 2011 收藏 引用 批量引用 报错 分享 ...
The mechanism that leads to the mode softening is reminiscent of the driving force inducing Peierls distortions, but the energy gained by opening the gap is not sufficient for a static lattice distortion. Instead, the corresponding vibrational frequency is lowered.Kresse...
In all cases, the periodic lattice distortion can be associated to a 2kF Peierls instability of the perylene chains. The Ni compound shows in addition to the 2kF distortion also a lattice instability at twice this wave vector, which corresponds to a dimerization of the Ni(mnt)2 chain of ...
