Magnetic Bloch Oscillations and domain wall dynamics in a near-Ising ferromagnetic chain

Autor: Hansen, Ursula B., Syljuåsen, Olav F., Jensen, Jens, Schäffer, Turi K., Andersen, Christopher R., Rodriguez-Rivera, Jose A., Christensen, Niels B., Lefmann, Kim

When charged particles in periodic lattices are subjected to a constant electric field, they respond by oscillating. Here we demonstrate that the magnetic analogue of these Bloch oscillations are realised in a one-dimensional ferromagnetic easy axis

Publikováno v: Jensen, J, Larsen, J & Hansen, U B 2018, ' Comprehensive cluster-theory analysis of the magnetic structures and excitations in CoCl 2 ·2H 2 O ', Physical Review B, vol. 97, no. 2, 024423 . https://doi.org/10.1103/PhysRevB.97.024423

The magnetic properties of CoCl2·2H2O are analyzed in the mean-field/random-phase approximation using a basis of clusters with four spins along the c-axis chains of Co ions. The model gives a unifying account of the bulk properties, the spin waves,
