复杂亚铁磁体的量子热力学
Quantum thermodynamics of complex ferrimagnets
摘要：
高质量的磁铁，如钇铁石榴石（YIG）是电绝缘的，非常复杂。通过在原子自旋动力学中实现量子恒温器，我们计算了YIG的关键热力学性质，即磁振子功率谱和比热，在很大的温度范围内。结果不同于简单模型和经典统计，但与现有的实验数据一致。
英文摘要：
High-quality magnets such as yttrium iron garnet (YIG) are electrically insulating and very complex. By implementing a quantum thermostat into atomistic spin dynamics we compute YIG's key thermodynamic properties, viz. the magnon power spectrum and specific heat, for a large temperature range. The results differ (sometimes spectacularly) from simple models and classical statistics, but agree with available experimental data.
