During the pandemic, research continues... Even if the labs are closed, theoretical work can still be done to complement the experimental work and to answer our questions about why things happen the way they do in the real life!
Micromagnetic simulation is a theoretical(numerical) method that is used to model magnetic systems such as magnetic tunnel junctions (MTJs, that are used in magnetic sensors and memories). Dr. Beik Mohammadi and her collaborator at NYU investigated magnetic tunnel junctions with micromagnetic simulations. This work lead to the publication of "Spin-torque switching mechanisms of perpendicular magnetic tunnel junction nanopillars" paper that just published in the Applied Physics Letter journal and selected as an Editor's Pick.
