This technical note explains how spatial resolution is defined in Scanning NV Magnetometry. For a given distance d between the NV center and the scanned surface, the best achievable lateral spatial resolution is 0.86 d.
Swastik Kar’s group at Northeastern University used AC magnetometry on the Qnami ProteusQ to show that a permalloy nanowire can be used to concentrate RF fields into sub 300nm regions.
Led by Mark Ku at the University of Delaware, this work characterizes a high-quality diamond micro-chip from the Qnami Quantum Foundry for advanced, high-resolution NV-based quantum microscopy.
