Field-tunable interactions and frustration in underlayer-mediated artificial spin ice
Susan Kempinger, Yu-Sheng Huang, Paul Lammert +5
Artificial spin ice systems have opened experimental windows into a range of model magnetic systems through the control of interactions among nanomagnet moments. This control has p…
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…
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…
Giant Anisotropic Magnetoresistance in a Quantum Anomalous Hall Insulator
A. Kandala, A. Richardella, S. Kempinger +2
When a three-dimensional (3D) ferromagnetic topological insulator thin film is magnetized out-of-plane, conduction ideally occurs through dissipationless, one-dimensional (1D) chir…
