I will discuss our recent results using tunneling magnetoresistance and spectroscopy to probe the underlying magnetic order and/or excitations in two “complex” atomically thin spin systems: the Kitaev material alpha-RuCl3 in monolayer form and twisted bilayers of the layer antiferromagnet CrI3. We find a reversal of the magnetic anisotropy together with an enhancement of the Kitaev interaction in the former and multiple skyrmion states in the latter that can be tuned by magnetic field.
**Refreshments will be served in the Olin lobby beginning at 3:30 pm
