磁特性科学实验站主要研究和探索量子磁性、低维阻挫、多铁性材料、功能磁性、磁性拓扑材料等诸多磁性材料在低温强磁场条件下的磁相变、铁电相变、量子相变，以及极端条件诱导出的新奇量子物态。

1、测量条件

•测量温度：氦四系统1.5-300K；氦三系统0.5-4.2K

•磁场强度：单线圈磁体0-60T；双线圈磁体0-80T

•磁场脉宽：单线圈磁体<50ms；双线圈磁体>200ms

2、实验手段

•磁化强度：采用电磁感应测量方法（10^-4emu），实验原理参见《物理》45卷1期19-25（2016）“脉冲强磁场磁特性科学测量系统及其应用”。

•电极化：采用热释电流测量方法（0.1mC/m²），实验原理参见《物理学报》69卷5期057502（2020）“脉冲强磁场下的电极化测量系统”。

•磁致伸缩：基于布拉格光栅法（DL/L <10^-4），结合脉冲场等极端条件测量物质在强磁场下的应变和磁弹效应。
