The quantum states of diamond's nitrogen-vacancy (NV) center have demonstrated their ability to sense magnetic fields, electric fields, and temperatures. One of the interesting systems to develop is a scanning NV probe microscopy with a pillar-shaped diamond probe containing NV centers at the apex of a diamond. This enables local probing and imaging of magnetic structures and spin dynamics, including electron spin and nuclear magnetic spin. On the other hand, this scanning NV magnetometry probe has drawbacks regarding durability, reduction of background spin noises inside and surface of the diamond pillar probe. The probable methods to treat diamond pillar probes' surface with ozone exposure, plasma etching, and so on, for solving these problems and achieving high-quality scanning NV probes were investigated.
