Determination of the exchange anisotropy in perovskite antiferromagnets using powder inelastic neutron scattering
R. J. McQueeney, J. -Q. Yan, S. Chang +1
A procedure is outlined for the determination of magnetic exchange constants in anisotropic perovskite anitferromagnets using powder inelastic neutron scattering. Spin wave densiti…
Zener double exchange from local valence fluctuations in magnetite
R. J. McQueeney, M. Yethiraj, S. Chang +4
Magnetite (FeO) is a mixed valent system where electronic conductivity occurs on the B-site (octahedral) iron sublattice of the spinel structure. Below 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…
Magnetic structure of antiferromagnetic NdRhIn5
S. Chang, P. G. Pagliuso, Wei Bao +4
The magnetic structure of antiferromagnetic NdRhIn5 has been determined using neutron diffraction. It has a commensurate antiferromagnetic structure with a magnetic wave vector (1/…
