几何阻挫磁性分子本征值的近似确定

Approximate eigenvalue determination of geometrically frustrated magnetic molecules

R. Schnalle, A. Laeuchli, J. Schnack

摘要:

几何阻挫磁性分子在分子磁学领域和海森堡反铁磁体领域都引起了广泛的兴趣。在这篇文章中,我们演示了如何使用近似对角化方案,以获得有关受抑磁性分子的热力学和光谱信息。为此,我们从理论上研究了一个具有立方八面体结构的反铁磁耦合自旋系统。

英文摘要:

Geometrically frustrated magnetic molecules have attracted a lot of interest in the field of molecular magnetism as well as frustrated Heisenberg antiferromagnets. In this article we demonstrate how an approximate diagonalization scheme can be used in order to obtain thermodynamic and spectroscopic information about frustrated magnetic molecules. To this end we theoretically investigate an antiferromagnetically coupled spin system with cuboctahedral structure modeled by an isotropic Heisenberg Hamiltonian.
