We investigated the spin excitations of magnetoelectric LiFePO4 by THz absorption spectroscopy in magnetic fields up to 33 T. By studying their selection rules, we found not only magnetic-dipole, but also electric-dipole active (electromagnons) and m

Magnesium (Mg) atoms in interstitial positions of a silicon host lattice form double donor centers. The binding energy of the neutral $\mathrm{M}{\mathrm{g}}^{0}$ state corresponds to midinfrared wavelengths. Due to its interstitial character, the ou

Interaction of low-energy electronic excitation of Tm3+ions with acoustic vibrations in crystal KTm (MoO4)2

Autor: D. L. Kamenskyi, V. I. Kut'ko, S. N. Poperezhai

Publikováno v: SPIE Proceedings.

Long-wave IR transmission spectra of crystal KTm(MoO4)2 have been measured in polarized light (Е║а and Е║с) at T=6К in the energy range 10-40 cm-1. Two vibration modes with energy 18.5 cm-1 in polarization Е║а and with energy 25.5 cm-1 i
