Disentangling orbital and spin exchange interactions for Co${}^{2+}$ on a rocksalt lattice

P. M. Sarte, R. A. Cowley, E. E. Rodriguez +14

Neutron spectroscopy was applied to study the magnetic interactions of orbitally degenerate Co${}^{2+}$ on a host MgO rocksalt lattice where no long range spin or orbital order exist…
