Imaging the stochastic microstructure and dynamic development of correlations in perpendicular artificial spin ice

Imaging the stochastic microstructure and dynamic development of correlations in perpendicular artificial spin ice

We use spatially resolved magneto-optical Kerr microscopy to track the complete microstates of arrays of perpendicular anisotropy nanomagnets during magnetization hysteresis cycles. These measurements, along with our statistical methodology, allow us to disentangle the intertwined effects of nearest...
