Grutter is recognized for elucidating the mechanisms by which ferromagnetic order in a magnetic topological insulator can be stabilized and manipulated via interfacial coupling with an antiferromagnet. Through a series of challenging and exceptionally precise neutron scattering measurements, Grutter identified the interfacial spin configuration that enhances technologically critical magnetic properties, the most important of which is a drastic increase in the temperature at which ferromagnetism can be sustained in the topological insulator.
