We investigated theoretically the thermo-induced spin transition of a nanostructure made of an active spin crossover core surrounded by an inert shell with a misfit of lattice parameters between the two constituents. The structural and magnetic features of the SCO core are very sensitive to the structural properties of the surrounding environment. The misfit of lattice parameters influences the nature of the spin transition from gradual to abrupt one with an important shift of the transition temperature. The mechanical properties of the nanoparticle were as well studied and correlated with the magnetic behaviour of the nanoparticle.

自旋交叉核/壳纳米粒子热力学性能的电弹性建模

我们在理论上研究了由活性自旋交联核构成的纳米结构的热诱导自旋跃迁，该活性自旋交越核被惰性壳包围，两种成分之间的晶格参数不匹配。SCO磁芯的结构和磁特性对周围环境的结构特性非常敏感。晶格参数的失配会影响自旋转变从渐变到突然转变的性质，并且转变温度发生重要变化。还研究了纳米颗粒的机械性能，并将其与纳米颗粒的磁行为相关联。
