Imaging the stochastic microstructure and dynamic development of correlations in perpendicular artificial spin ice
Susan Kempinger, Robert D. Fraleigh, Paul Lammert +4
We use spatially resolved magneto-optical Kerr microscopy to track the complete microstates of arrays of perpendicular anisotropy nanomagnets during magnetization hysteresis cycles…
Engineering the breaking of time-reversal symmetry in gate-tunable hybrid ferromagnet/topological insulator heterostructures
Joon Sue Lee, Anthony Richardella, Robert D. Fraleigh +3
Studying the influence of breaking time-reversal symmetry on topological insulator surface states is an important problem of current interest in condensed matter physics and could…
Characterization of switching field distributions in Ising-like magnetic arrays
Robert D. Fraleigh, Susan Kempinger, Paul Lammert +4
The switching field distribution within arrays of single-domain ferromagnetic islands incorpo- rates both island-island interactions and quenched disorder in island geometry. Separ…
