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…
Spin scattering and noncollinear spin structure-induced intrinsic anomalous Hall effect in antiferromagnetic topological insulator
Seng Huat Lee, Yanglin Zhu, Yu Wang +8
has recently been established as an intrinsic antiferromagnetic (AFM) topological insulator and predicted to be an ideal platform to realize quantum anomalous…
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…
Visualization of superparamagnetic dynamics in magnetic topological insulators
E. Lachman, A. F. Young, A. Richardella +10
Quantized Hall conductance is a generic feature of two dimensional electronic systems with broken time reversal symmetry. In the quantum anomalous Hall state recently discovered in…
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…
