Spin canting and lattice symmetry in LaCuO
Xiao Hu, A. Sapkota, V. O. Galea +3
While the dominant magnetic interaction in LaCuO is superexchange between nearest-neighbor Cu moments, the pinning of the spin direction depends on weak anisotropic effects…
Highly dispersive magnons with spin-gap like features in the frustrated ferromagnetic S=1/2 chain compound Ca2Y2Cu5O10 detected by inelastic neutron scattering
M. Matsuda, J. Ma, V. O. Garlea +10
We report inelastic neutron scattering experiments in Ca2Y2Cu5O10 and map out the full one magnon dispersion which extends up to a record value of 53 meV for frustrated ferromagnet…
Crystal Field Levels and Magnetic Anisotropy in the Kagome Compounds , , and
A. Scheie, M. Sanders, J. Krizan +4
We report the crystal field levels of several newly-discovered rare-earth kagome compounds: , , and . We…
Non-Fermi surface nesting driven commensurate magnetic ordering in Fe-doped SrRuO
M. Zhu, K. V. Shanavas, Y. Wang +11
SrRuO, an unconventional superconductor, is known to possess an incommensurate spin density wave instability driven by Fermi surface nesting. Here we report a static spin d…
Unusual UUDD magnetic chain structure of the spin-1/2 tetragonally distorted spinel GeCu2O4
T. Zou, Y. -Q. Cai, C. R. dela Cruz +4
GeCu2O4 exhibits a tetragonal spinel structure due to the strong Jahn-Teller distortion associated with Cu2+ ions. We show that its magnetic structure can be described as slabs com…
