AC magnetometry of van der Waals magnets using ultrasensitive Graphene Hall sensors
Eugene Park, Jihoon Keum, Ji-Hwan Baek +5
Probing the dynamical magnetic properties of two-dimensional (2D) materials requires sensitive techniques capable of detecting small magnetic fields from nanoscale samples. We demo…
