    • Conservation of angular momentum in ultrafast spin dynamics 

      Sanvito, Stefano (2022)
      The total angular momentum of a closed system is a conserved quantity, which should remain constant in time for any excitation experiment once the pumping signal has been extinguished. Such conservation, however, is never ...

    • Ultrafast Double Pulse All-Optical Reswitching of a Ferrimagnet 

      Coey, John; Stamenov, Plamen; Rode, Karsten; Atcheson, Gwenael (2021)
      All-optical reswitching has been investigated in the half-metallic Heusler ferrimagnet Mn2Ru0.9Ga, where Mn atoms occupy two inequivalent sites in the XA-type structure. The effect of a second 200 fs, 800 nm laser pulse ...
