摘要:

我们利用金刚石中氮空位(NV)中心自旋之间的可调偶极相互作用来旋转金刚石晶体。具体来说,我们采用交叉弛豫之间的电子自旋的NV中心对被困的金刚石,以提高各向异性NV顺磁性,从而增加相关的自旋扭矩。我们的观察打开了一条道路,使用机械振荡器检测顺磁缺陷,缺乏光学跃迁,调查角动量守恒的自旋弛豫过程和冷却机械振荡器的运动的新手段。

英文摘要:

We use tunable dipolar-interactions between the spins of nitrogen-vacancy (NV) centers in diamond to rotate a diamond crystal. Specifically, we employ cross-relaxation between the electronic spin of pairs of NV centers in a trapped diamond to enhance the anisotropic NV paramagnetism and thus to increase the associated spin torque. Our observations open a path towards the use of mechanical oscillators to detect paramagnetic defects that lack optical transitions, to investigation of angular momentum conservation in spin relaxation processes and to novel means of cooling the motion of mechanical oscillators.
