Quantum kagome spin liquids: a local view

Semion wave function and energetics in a chiral spin liquid on the Kagome lattice

Recent years have seen the discovery of a chiral spin liquid state – a bosonic analogue of a fractional Quantum Hall state first put forward by Kalmeyer and Laughlin in 1987 – in several deformations of the Heisenberg model on the Kagome lattice. Here, we apply state-of-the-art numerical techniques to one such model, where breaking of the time-reversal symmetry drives the system into the chiral...

Modification of the thermal spin-wave spectrum in a Ni81Fe19 stripe by a domain wall

The thermal spin-wave distribution in a Ni81Fe19 stripe with an asymmetric transverse domain wall has been investigated using Brillouin light scattering microscopy. Clear evidence has been found that the existence of the domain wall influences the spin-wave distribution of the thermal modes. The thermal spinwave modes in the Ni81Fe19 structures, which are quantized due to the confinement in rad...

Spin-Wave Spectra of Yttrium and Gadolinium Iron Garnet

The problem of deducing the values of the exchange integrals in yttrium and gadolinium iron garnet from measurements of the magnetization and the magnetic contribution to the specific heat at low temperatures is considered. For these garnets the spin-wave normal modes can be found by solving the semiclassical equations of motion which give rise to a set of n simultaneous linear equations, where...
