The project develops a new method by exploiting the unique sensitivity of nitrogen-vacancy (NV) centers in diamond to magnetic fields, mechanical strain and temperature to optically read out local strain fields. The potential of this method is demonstrated for antiferromagnetic thin films with a non-collinear magnetic structure and strong magnetoelastic coupling deposited on thin diamond membranes. The method will be also available for other CRC/TRR projects.

该项目开发了一种新方法，利用金刚石中氮空位（NV）中心对磁场、机械应变和温度的独特敏感性，以光学方式读出局部应变场。这种方法的潜力被证明为反铁磁薄膜与非共线的磁性结构和强磁弹性耦合沉积在薄金刚石膜。该方法也可用于其他CRC/TRR项目。
