Where: 
Room G59, Old Main Building, UNSW Kensington Campus

The talk will give an overview of our work on the coupling of NV centers with diamond mechanical resonators. This covers the different coupling mechanisms of the NV center such as strain mediated coupling and magnetic field coupling under mechanical as well as laser actuated driving of the oscillator. Finally, we will discuss preliminary results on scanning probe magnetometry at cryogenic temperatures where we look at the helical phase of the skyrmion host material Cu2OSeO3
