论文摘要
分子磁体晶体中的分流过程是相互作用的电子自旋系统的典型的。我们分析了在二磁单晶体中稀释的原型TBPC $ _2 $复合物的Landau-Zener动力学。在最近提出的主方程的框架中,评估了隧道概率对场扫描速率的依赖性,在该框架中,通过现象学lindblad操作员来描述了分解过程。因此,我们展示了低温磁性测量值,这些测量在确定小型隧道分裂和脱落时间时补充了谐振技术。
Decoherence processes in crystals of molecular magnets are prototypical for interacting electronic spin systems. We analyze the Landau-Zener dynamics of the archetypical TbPc$_2$ complex diluted in a diamagnetic monocrystal. The dependence of the tunneling probability on the field sweep rate is evaluated in the framework of the recently proposed master equation in which the decoherence processes are described through a phenomenological Lindblad operator. Thus, we showcase low temperature magnetic measurements that complement resonant techniques in determining small tunnel splittings and dephasing times.
