Zener double exchange from local valence fluctuations in magnetite

R. J. McQueeney, M. Yethiraj, S. Chang +4

Magnetite (Fe $_{3}$ O $_{4}$ ) is a mixed valent system where electronic conductivity occurs on the B-site (octahedral) iron sublattice of the spinel structure. Below $T_{V} = 122$ K, a…

Damping of antiferromagnetic spin waves by valence fluctuations in the double layer perovskite YBaFe2O5

S. Chang, P. Karen, M. P. Hehlen +2

Inelastic neutron scattering experiments show that spin dynamics in the charge ordered insulating ground state of the double-layer perovskite YBaFe2O5 is well described in terms of…
