Valence bond crystal in a pyrochlore antiferromagnet with orbital degeneracy
S. Di Matteo, G. Jackeli, C. Lacroix +1
We discuss the ground state of a pyrochlore lattice of threefold-orbitally-degenerate magnetic ions. We derive an effective spin-orbital Hamiltonian and show that the orbit…

Kagome spin ice
A. S. Wills, R. Ballou, C. Lacroix
A new model of localized highly frustrated ferromagnetism is presented: kagome spin ice. By use of analytical and Monte Carlo calculations its massive groundstate entropy is evalua…

Extraordinary Hall effect in hybrid ferromagnetic/superconductor (F/S) bilayer
N. Ryzhanova, B. Dieny, C. Lacroix +2
Extraordinary Hall effect (EHE) in bilayer F/S(N) was investigated theoretically. The conductivity tensor is calculated in the Kubo formalism with Green functions found as…
