Magnetic noise detection and imaging from a superparamagnetic core-shell particle via an ensemble of nitrogen-vacancy centers in a thin diamond chip
We describe a local fluctuating magnetic field detection of Fe _3 O _4 superparamagnetic core–shell particles via relaxometry of an ensemble of NV centers in a diamond. A thin diamond chip enables optical access to the contact position of the magnetic particle through the backside. A significant dro...
