    This paper summarizes recent investigations of the magnetic excitations of the spin density wave (SDW) in pure Cr in both the low temperature longitudinally polarized phase (T. 5 SPIN WAVES IN THE FERROMAGNETIC HEAVY RARE EARTHS The ferromagnetic hcp-crystal Spin waves in the anisotropic ferromagnet The uniform mode and spin-wave theory The magnetic susceptibility and the energy gap The validity of the spin-wave theory Magnetoelastic effects

    A recent inelastic neutron scattering experiment on the pyrochlore magnet Yb 2 Ti 2 O 7 uncovers an unusual scattering continuum in the spin excitation spectrum despite the splayed ferromagnetic order in the ground state. While there exist well defined spin wave excitations at high magnetic fields, the one magnon modes and the two magnon continuum start to strongly overlap upon decreasing the. ().

Calculations for χ(K⇒,ω) at low temperatures predict a spin wave mode that rises to intersect a Stoner band of excitations. We have made neutron‐inelasti‐scattering measurements which confirm this overall picture while providing details such as the spin wave dispersion and the.

BOROVIK-ROMANOV and S.K. SINHA (Eds.) ``Spin Waves and Magnetic Excitations'' describes both simple spin waves (magnons) and complicated excitations in magnetic systems. Wide classes of magnetic substances are taken into consideration such as ferro- and antiferromagnetic dielectrics and itinerant magnets which contain both d- and f-electrons.

We develop a self-consistent theory for current-induced spin wave excitations in normal metal-magnetic insulator bilayer systems, thereby establishing the relation between spin wave. The book can be divided into three major parts.

The first is comprised of Chapters and is concerned with the physics of magnetism and electromagnetic waves in magnetic media. Spin waves and magnetic excitations book second part, Chaptersfocuses on magnetostatic modes and dipolar spin waves, their properties, how to excite them, and how they interact with light.

Spin Waves: Theory and Applications covers topics foundational to understanding spin waves such as the physics of magnetism and electromagnetic waves in anisotropic media, as well as both classical and quantum mechanical treatments of spin wave excitations.

The authors discuss many applications including microwave delay lines, spin wave-optical devices, and microwave oscillations induced by.

Modern Problems in Condensed Matter Sciences, Volume Spin waves are propagating disturbances in the ordering of magnetic materials.

These low-lying collective excitations occur in magnetic lattices with continuous the equivalent quasiparticle point of view, spin waves are known as magnons, which are bosonic modes of the spin lattice that correspond roughly to the phonon excitations of the nuclear lattice.

excitations are related to different terms of the Hamiltonian describing the magnetic system: spin-orbit coupling, crystal field potential, exchange interaction. The bulk of the topic of magnetic excitations is covered by the review article of Stirling and McEwen [1].

Magnons are collective spin excitations in crystals with long-range magnetic order. The emergent van der Waals magnets1–3 provide a highly tunable platform to explore magnetic excitations.

Vol. Elsevier, New York, Modern Problems in Condensed Matter Sciences, 22 pt Spin waves are collective magnetic excitations. They can be described in two different pictures: the classical Heisenberg model based on the localized moment approximation and the itinerant electron model [30].

This section will be focused on the description of the spin waves in the classical Heisenberg model, which gives an intuitive picture. Most standard textbooks on Solid State Theory contain a chapter on spin waves or magnons and magnetic properties, but there are also special review articles [, ] and monographs [, –] on these topics.

In addition, the change of the spin-wave (SW) parameter B 3 ∕ 2 versus t Co was discussed. The torque magnetometry was utilized to extract the effective anisotropy (K eff) and the interlayer coupling constant (J I) was determined from the in-plan M–H loops.

From the Inside Flap The aim of this advanced textbook is to provide the reader with a comprehensive explanation of the ground state configurations, the spin wave excitations and the equilibrium properties of spin lattices described by the Ising Heisenberg Hamiltonians in the presence of short (exchange) and long range (dipole) : Enrico Rastelli.

They prove to be of a key importance for the vortex switching [ 25 ], can be used to generate the higher harmonics of the microwave radiation [ 26 ], and have a significant influence on the vortex stability [ 27, 28 ].SP 15 Spin waves and magnonics.
