结构相变是为与组成相变相区别而命名的。凡是由于温度、压力、各种物理场等的改变而引起的结构状态的变化称为结构相变。结构相变分为两个基本类型,重构型和位移型,这样的分类是基于形成周期性网格的化学键经相变后受到破坏与否。
Moreover, a lot of new physical phenomena have also been observed in these compounds, recently, such as the large magnetostriction, structural phase transition driven by an external field, and anomalousthermal expansion, etc.
最近几年里,在该类材料中还相继发现了许多新的物理现象,例如:大的磁致伸缩、磁致结构相变以及在相变温度附近异常的热膨胀等。
