NV-center spectroscopy for strain sensing of non-collinear antiferromagnets (A08+)

该项目开发了一种新的方法，利用钻石中氮空位(NV)中心对磁场、机械应变和温度的独特敏感性来光学读取局部应变场。对于沉积在金刚石薄膜上的具有非共线磁性结构和强磁弹耦合的反铁磁性薄膜，证明了该方法的潜力。该方法也将适用于其他儿童权利中心/TRR项目。

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.
