    • Antiferromagnetic single-layer spin-orbit torque oscillators 

      Stamenov, Plamen; Rode, Karsten; Coey, John (2019)
      We show how a charge current through a single antiferromagnetic layer can excite and control self-oscillations. Sustained oscillations with tunable amplitudes and frequencies are possible in a variety of geometries using ...

    • 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 ...

    • Data-driven time propagation of quantum systems with neural networks 

      Sanvito, Stefano (2022)
      We investigate the potential of supervised machine learning to propagate a quantum system in time. While Markovian dynamics can be learned easily, given a sufficient amount of data, non-Markovian systems are nontrivial and ...

    • Role of longitudinal fluctuations in L10 FePt 

      Sanvito, Stefano; Ellis, Matthew O.A.; Galante, Mario (American Physical Society (APS), 2019)
      L10 FePt is a technologically important material for a range of novel data storage applications. In the ordered FePt structure the normally nonmagnetic Pt ion acquires a magnetic moment, which depends on the local field ...

    • Structural, magnetic, and spin dynamical properties of the polar antiferromagnets Ni3—xCoxTeO6(x=1,2) 

      Skiadopoulou, Styliani (2020)
      We present results of a multimethod investigation of the polar antiferromagnets Ni2CoTeO6 and NiCo2TeO6, inspired by the colossal magnetoelectric effect present in Ni3TeO6. Both compounds crystalize in the same polar space ...
