Heat accumulation and all-optical switching by domain wall motion in   Co/Pd superlattices
  All-optical switching by domain wall motion has been observed in Co/Pd superlattices. Heat accumulation is part of the switching process for our experimental conditions. Numerical calculations point to a connection between domain wall motion and in-plane heat diffusion.
