Abstract:

Artificial spin ice refers to an array of elongated ferromagnetic elements that is built using e-beam lithography. Originally conceived as a two-dimensional analogue of spin ice, artificial spin ice displays a variety of fascinating physical phenomena induced by geometrical frustration and has become an independent research area in its own right. The advantage of artificial spin ice compared to its natural counterpart is that one can vary the interaction strength and geometry at will. In this talk, I will give a general overview of the research field and cover some of my own results that are related to the magnetic reversal of artificial spin ice.
