Spin-lattice coupling in frustrated antiferromagnets
We review the mechanism of spin-lattice coupling in relieving the geometrical frustration of pyrochlore antiferromagnets, in particular spinel oxides. The tetrahedral unit, which is the building block of the pyrochlore lattice, undergoes a spin-driven Jahn-Teller instability when lattice degrees of freedom are coupled to the antiferromagnetism. By restricting our considerations to distortions w...
متن کاملMagnonic charge pumping via spin-orbit coupling.
The interplay between spin, charge and orbital degrees of freedom has led to the development of spintronic devices such as spin-torque oscillators and spin-transfer torque magnetic random-access memories. In this development, spin pumping represents a convenient way to electrically detect magnetization dynamics. The effect originates from direct conversion of low-energy quantized spin waves in ...
متن کاملSpin-lattice coupling as environmental effect
The exchange constant in a magnetic system results from the overlap of orbitals, so it depends upon the ion distance and yields a coupling with the lattice vibrations: this can strongly influence the statistical mechanics of magnets. As the fast lattice dynamics allows for a rapid thermalization, phonon-induced spin correlations can be reasonably neglected, so that phonons can be regarded as a ...
متن کاملTheory of thermal spin-charge coupling in electronic systems
The interplay between spin transport and thermoelectricity offers several novel ways of generating, manipulating, and detecting nonequilibrium spin in a wide range of materials. Here, we formulate a phenomenological model in the spirit of the standard model of electrical spin injection to describe the electronic mechanism coupling charge, spin, and heat transport and employ the model to analyze...
متن کاملCoupling of spin waves with charge- and spin-density excitations in spin-polarized quantum wells
The coupling of spin waves with chargeand spin-density waves is shown to be induced by a spin-dependent interaction in a quantum well, which is spin polarized by a dc magnetic field at an angle u to the symmetry axis. The mixing of the plasmonic and magnonic modes, which occurs for both intraand intersubband transitions, depends on the coupling constant of the spin-spin interaction, the tilt an...
