Spin-Wave Wave Function for Quantum Spin Models [PDF]

open access: yesProgress of Theoretical Physics, 1997
We present a new approach to determine an accurate variational wave function for general quantum spin models, completely defined by a consistency requirement with the simple and well­ known linear spin·wave expansion. With this wave function, it is also possible to obtain the correct behavior of the long distance correlation functions for the 1D S=1/2 ...

Spin Waves in Quasiequilibrium Spin Systems [PDF]

open access: yesPhysical Review Letters, 2006
Using the Landau Fermi liquid theory we have discovered a new regime for the propagation of spin waves in a quasi-equilibrium spin systems. We have determined the dispersion relation for the transverse spin waves and found that one of the modes is gapless.

Magnetoelectric spin wave amplifier for spin wave logic circuits [PDF]

open access: yesJournal of Applied Physics, 2009
We propose and analyze a spin wave amplifier aimed to enhance the amplitude of the propagating spin wave via the magnetoelectric effect. The amplifier is a two-layer multiferroic structure, which comprises piezoelectric and ferromagnetic materials. By applying electric field to the piezoelectric layer, the stress is produced.

Spin waves in random spin chains [PDF]

open access: yesJournal of Applied Physics, 2003
We study quantum spin-1/2 Heisenberg ferromagnetic chains with dilute random antiferromagnetic impurity bonds with the modified spin-wave theory. By describing thermal excitations in the language of spin waves, we observe a low-temperature Curie susceptibility due to the formation of large spin clusters first predicted by the real-space renormalization-

Confined dipole and exchange spin waves in a bulk chiral magnet with Dzyaloshinskii-Moriya interaction

open access: yesPhysical Review Research, 2021
The Dzyaloshinskii-Moriya interaction (DMI) has an impact on excited spin waves in the chiral magnet Cu_{2}OSeO_{3} by means of introducing asymmetry in their dispersion relations.

Engineering structured magnetic bits for magnonic holographic memory

open access: yesAIP Advances, 2023
Magnonic holographic memory is a type of memory that uses spin waves for magnetic bit read-in and read-out. Its operation is based on the interaction between magnets and propagating spin waves where the phase and the amplitude of the spin wave are ...
