Abstract
A magnetometer includes a tapered microfiber having a curved portion, an excitation laser in optical communication with the tapered microfiber, and a nanocrystal attached to the curved portion of the tapered microfiber. Laser light emitted from the excitation laser interacts with the nanocrystal to create an emitted photon flux which is monitored to detect a magnetic field passing through the nanocrystal.
