متن کاملSpin-phonon coupling in antiferromagnetic chromium spinels
The temperature dependence of eigenfrequencies and intensities of the IR active modes has been investigated for the antiferromagnetic chromium spinel compounds CdCr2O4, ZnCr2O4, ZnCr2S4, ZnCr2Se4, and HgCr2S4 by IR spectroscopy for temperatures from 5 K to 300 K. At the transition into the magnetically ordered phases, and driven by spin-phonon coupling, most compounds reveal significant splitti...
متن کاملPeierls Dimerization with Nonadiabatic Spin-Phonon Coupling
We study the magnetic properties of a frustrated Heisenberg spin chain with a dynamic spin-phonon interaction. Using Lanczos diagonalization that preserves the full lattice dynamics, we explore the nonadiabatic regime with phonon frequencies comparable to the exchange coupling energy, which is, for example, the relevant limit for the spin-Peierls compound CuGeO3. Compared to the static limit of...
متن کاملHeat Transport in Spin Chains with Weak Spin-Phonon Coupling.
The heat transport in a system of S=1/2 large-J Heisenberg spin chains, describing closely Sr(2)CuO(3) and SrCuO(2) cuprates, is studied theoretically at T≪J by considering interactions of the bosonized spin excitations with optical phonons and defects. Treating rigorously the multiboson processes, we derive a microscopic spin-phonon scattering rate that adheres to an intuitive picture of phono...
متن کاملSpin-Phonon Coupling in High-Tc Copper Oxides
Band calculations on HgBa2CuO4 and La(2−x)SrxCuO4 with phonon and spin-waves within the CuO planes show that partial gaps are created at various energies depending on wavelengths. Spin and phonon gaps appear at different energies when the modulations are along [1,1,0], while they are at the same energy for modulations along [1,0,0]. It is shown that the ability to form gaps and antiferromagneti...
