Abstract

A Gadolinium EDTA chelate displays characteristic isotropic behaviour common of Gd(III) complexes under zero applied magnetic field, and anisotropic behaviour arising from dipolar coupling and weak spin-phonon coupling under an applied magnetic field. This surprising magnetic behaviour for Gd(III) is investigated using SQUID magnetometry and rationalized through theoretical calculations.

摘要

钆乙二胺四乙酸螯合物在零外加磁场下表现出钆（III）配合物常见的各向同性行为，在施加磁场下则表现出由偶极耦合和弱自旋-声子耦合引起的各向异性行为。利用超导量子干涉仪磁力测定法研究了钆（III）这种惊人的磁行为，并通过理论计算进行了合理解释。
