Magnetization Dynamics in Magnetic Tunnel Junction Artificial Spin Ice - Dataset

This dataset contains experimental and simulation data for superparamagnetic tunnel junctions arranged in artificial spin ice arrays. Experimental tunnel magnetoresistance (TMR) data for individual devices in the arrays were collected with an RHK R9 conductive atomic force microscope. TMR hysteresis loops are provided for the two types of behavior observed in the array, termed X and Y devices. Micromagnetic simulations explore the effects of nearest-neighbor and next-nearest-neighbor interactions on a central Y device, including canting, and provide insight into the underlying magnetostatic interactions.
