High temperature emissivity, reflectivity, and x-ray absorption of BiFeO3
Massa, Néstor E.; Del Campo, Leire; Meneses, Domingos de Souza; Echegut, Patrick; Fabbris, Gilberto Fernandes Lopes; Azevedo, Gustavo de Medeiros; Martínez Lope, María Jesús; Alonso, José Antônio (2010) [Journal article]We report on the lattice evolution of BiFeO3 as function of temperature using far infrared emissivity, reflectivity, and x-ray absorption local structure. A power law fit to the lowest frequency soft phonon in the magnetic ...
