In our most recent work conducted in collaboration with our colleagues at the Institute of Electrical Engineering, Slovak Academy of Sciences, we look at the process of magnetic vortex nucleation in nanomagnets.
Magnetic vortices are characterized by polarity and chirality. We show that the vortex polarity and chirality in nanomagnets with broken rotational symmetry can be set independently by applying in-plane magnetic fields only. This is compatible with magnetic write-head media and could lead to significant increase of digital storage density since two bits of information (polarity and chirality) can be stored in a single memory element.
