The shape instability of magnetic domain walls under current is investigated in a ferromagnetic (Ga,Mn)(As,P) film with perpendicular anisotropy. Domain wall motion is driven by th…
Quantum tunneling of oxygen atoms on very cold surfaces
M. Minissale, E. Congiu, S. Baouche +7
Any evolving system can change of state via thermal mechanisms (hopping a barrier) or via quantum tunneling. Most of the time, efficient classical mechanisms dominate at high tempe…
