反铁磁分子中的阻挫效应:立方八面体

Frustration effects in antiferromagnetic molecules: the cuboctahedron

J. Schnack, R. Schnalle

摘要:

由竞争相互作用引起的磁性系统的挫折是几种不寻常现象的驱动力,例如磁化曲线的平台和跳跃,以及不寻常的能谱,例如低于第一三重态的许多单重态能级。反铁磁立方八面体可以作为某些受抑反铁磁体的典型例子。此外,它的优点是,它的完整的能谱可以获得的个人自旋量子数的s=3/2(16,777,216状态)。

英文摘要:

Frustration of magnetic systems which is caused by competing interactions is the driving force of several unusual phenomena such as plateaus and jumps of the magnetization curve as well as of unusual energy spectra with for instance many singlet levels below the first triplet state. The antiferromagnetic cuboctahedron can serve as a paradigmatic example of certain frustrated antiferromagnets. In addition it has the advantage that its complete energy spectrum can be obtained up to individual spin quantum numbers of s=3/2 (16,777,216 states).
