ABSTRACT In this work, we investigate the spin transformation from ferromagnetic austenite BCT lattice to antiferromagnetic martensite BCC lattice (ji = +J → ji = -J or ↑↑→↑↓) in Bain transformation (or Bain strain) by using effective field theory which is developed by Kaneyoshi. We find that the spin orientation changes the magnetic properties in the Bain BCT→BCC transformation. Therefore, we predict that material can memory their spin orientations in the austenite-martensite transformation similar to the shape memory effect in the shape memory materials. Since the austenite-martensite transformation mechanism is first modelled by Bain, we call this spin memory effect as 'Bain spin memory materials (BSMM)’.

Kaneyoshi 理论揭示的贝恩自旋记忆材料 (BSMM) 的预测

摘要 在这项工作中，我们使用有效场理论研究了贝恩变换（或贝恩应变）中从铁磁奥氏体 BCT 晶格到反铁磁马氏体 BCC 晶格（ji = +J → ji = -J 或 ↑↑→↑↓）的自旋转变这是由兼吉开发的。我们发现自旋方向改变了贝恩 BCT→BCC 转换中的磁性。因此，我们预测材料可以在奥氏体-马氏体转变中记忆它们的自旋方向，类似于形状记忆材料中的形状记忆效应。由于奥氏体-马氏体转变机制首先由贝恩建模，我们将这种自旋记忆效应称为“贝恩自旋记忆材料 (BSMM)”。
