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 vortex nucleation in nanomagnets. Magnetic vortices are formed in small magnetic structures. The vortices are characterized by a core with specific polarity and the in-plane curl of the moments around the…

Replacing expensive platinum as catalyst remains a tremendous obstacle for large-scale application of fuel-cell technology. In addition to high cost, pure Pt is neither the most active nor the most stable catalyst for fuel cell reactions. Specifically, the instability of Pt at the cathode side represents one of the major limitations for commercialization of this…
