-[Pd(dmit)] as a quasi-1D, scalene Heisenberg model
E. P. Kenny, A. C. Jacko, B. J. Powell
From first principles, we calculate the Heisenberg interactions between neighboring dimers in several compounds within the EtMe[Pd(dmit)] (Et = ethyl, Me = m…
The princess and the pea: on the outsized role of inter-layer ligands in copper-pyrazine antiferromagnets
E. P. Kenny, A. C. Jacko, B. J. Powell
We investigate the cause of exchange anisotropy in a family of copper-based, quasi-two-dimensional materials with very similar geometries. This family differs mainly in the inter-l…
Interplay of dipoles and spins in -(BEDT-TTF), where Hg(SCN)Cl, Hg(SCN)Br, Cu[N(CN)]Cl, Cu[N(CN)]Br, and Ag(CN)
A. C. Jacko, E. P. Kenny, B. J. Powell
We combine first principles density functional calculations with empirical relationships for the Coulomb interactions in the `monomer' model of -(BEDT-TTF). This enables us…
Frustration, ring exchange, and the absence of long-range order in EtMeSb[Pd(dmit)]: from first principles to many-body theory
E. P. Kenny, G. David, N. Ferré +2
We parameterize Hubbard and spin models for EtMeSb[Pd(dmit)] from broken symmetry density functional calculations. This gives a scalene triangular model where the large…
Towards mechanomagnetics in elastic crystals: insights from [Cu(acac)]
E. P. Kenny, A. C. Jacko, B. J. Powell
We predict that the magnetic properties of \cuacac, an elastically flexible crystal, change dramatically when the crystal is bent. We find that unbent \cuacac\ is an almost perfect…
Magnetic excitations of the Cu quantum spin chain in SrCuPtO
J. C. Leiner, Joosung Oh, A. I. Kolesnikov +10
We report the magnetic excitation spectrum as measured by inelastic neutron scattering for a polycrystalline sample of SrCuPtO. Modeling the data by the 2+4 spinon contribu…
