At interfaces between conventional materials, band bending and alignment are classically controlled by differences in electrochemical potential. Applying this concept to oxides in which interfaces can be polar and cations may adopt a mixed valence ha

Elastic and magnetic effects on the infrared phonon spectra of MnF2

Autor: Schleck, R., Nahas, Y., Lobo, R. P. S. M., Varignon, J., Lepetit, M. B., Nelson, C. S., Moreira, R. L.

Publikováno v: Phys. Rev. B 82, 054412 (2010)

We measured the temperature dependent infrared reflectivity spectra of MnF2 between 4 K and room temperature. We show that the phonon spectrum undergoes a strong renormalization at TN. The ab-initio calculation we performed on this compound accuratel
