The magnetic insulator Yttrium Iron Garnet can be grown with exceptional quality, has a ferrimagnetic transition temperature of nearly 600 K, and is used in microwave and spintronic devices that can operate at room temperature. The most accurate prior measurements of the magnon spectrum date back nearly 40 years, but cover only 3 of the lowest energy modes out of 20 distinct magnon branches. Here we have used time-of-flight inelastic neutron scattering to measure the full magnon spectrum… Expand

Spin Seebeck effect and ballistic transport of quasi-acoustic magnons in room-temperature yttrium iron garnet films
We studied the transient behavior of the spin current generated by the longitudinal spin Seebeck effect (LSSE) in a set of platinum-coated yttrium iron garnet (YIG) films of different thicknesses.Expand
Anisotropic bulk and planar Heisenberg ferromagnets in uniform, arbitrarily oriented magnetic fields.
This paper investigates the behaviour of an easy-plane and easy-axis anisotropic ferromagnet-both in two and three dimensions-subjected to a uniform magnetic field, applied along an arbitrary direction, and determines various magnetic properties such as the Curie temperature and the magnetization as a function ofTemperature and the applied magnetic field.

Magnon-phonon interactions in magnetic insulators
We address the theory of magnon-phonon interactions and compute the corresponding quasiparticle and transport lifetimes in magnetic insulators, with a focus on yttrium iron garnet at intermediateExpand
Detecting Light Dark Matter with Magnons.

Detectability of axion dark matter with phonon polaritons and magnons
Collective excitations in condensed matter systems, such as phonons and magnons, have recently been proposed as novel detection channels for light dark matter. We show that excitation of (i) opticalExpand
Momentum-Dependent Magnon Lifetime in the Metallic Noncollinear Triangular Antiferromagnet CrB_{2}.
The intrinsic magnon linewidth Γ(q,E_{q}) shows very unusual momentum dependence, which the analysis shows to originate from the combination of two-magnon decay and the Stoner continuum. Expand
Nonreciprocal magnons in a two-dimensional crystal with out-of-plane magnetization
Nonreciprocal spin waves have a chiral asymmetry so that their energy is different for two opposite wave vectors. They are found in atomically thin ferromagnetic overlayers with in-planeExpand
Observation of Magnon Polarization.
The observation of both signs of magnon polarization in Y_{3}Fe_{5}O_{12} also gives direct proof of its ferrimagnetic nature, and the experiments agree very well with atomistic simulations of the scattering cross section. Expand

Thermal Spin Dynamics of Yttrium Iron Garnet.
The method of atomistic spin dynamics is used to study the temperature evolution of the full spin wave spectrum, in quantitative agreement with neutron scattering experiments, and the antiferromagnetic or optical mode is found to suppress the spin Seebeck effect at room temperature and beyond due to thermally pumped spin currents with opposite polarization to the ferromagnetic mode.
