摘要

一个由三个自旋为（1/ 2,1 / 2,1）的磁性离子组成的分子磁体模型，由于朗德乘子的非均匀性而产生非保守磁化。本研究旨在解释系统在有限温度下磁化（退磁）过程中量子纠缠态的性质。我们展示了非均匀g因子的存在如何导致量子纠缠的显著增强，有时会导致模型中磁性离子的自旋（伪自旋）处于纠缠态的温度范围的扩大。

Quantum Entanglement in a Mixed Spin Trimer (1/2,1/2,1) with Non-Conserved Magnetization at Finite Temperatures

A model of a molecular magnet consisting of three magnetic ions with spins (1/2, 1/2, 1) and non-conserved magnetization arising due to the heterogeneity of Lande multipliers. This study aims to explain the properties of quantum entanglement of the states of the system during magnetization (demagnetization) processes at finite temperatures. We show how the presence of inhomogeneous g-factors results in a significant enhancement of quantum entanglement and sometimes the expansion of the temperature range in which the spins (pseudospins) of magnetic ions of the model are in entangled states.
