Gapless spinons and a field-induced soliton gap in the hyper-honeycomb Cu oxalate framework compound [(C $_{2}$ H $_{5}$ ) $_{3}$ NH] $_{2}$ Cu $_{2}$ (C $_{2}$ O $_{4}$ ) $_{3}$

C. Dissanayake, A. C. Jacko, K. Kumarasinghe +14

We report a detailed study of the specific heat and magnetic susceptibility of single crystals of a spin liquid candidate: the hyper-honeycomb Cu oxalate framework compound [(C $_{2}$ …

$x$ -[Pd(dmit) $_{2}$ ] $_{2}$ 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 Et $_{n}$ Me $_{4 - n} X$ [Pd(dmit) $_{2}$ ] $_{2}$ (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 $κ$ -(BEDT-TTF) $_{2} X$ , where $X =$ Hg(SCN) $_{2}$ Cl, Hg(SCN) $_{2}$ Br, Cu[N(CN) $_{2}$ ]Cl, Cu[N(CN) $_{2}$ ]Br, and Ag $_{2}$ (CN) $_{3}$

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 $κ$ -(BEDT-TTF) $_{2} X$ . This enables us…

Frustration, ring exchange, and the absence of long-range order in EtMe $_{3}$ Sb[Pd(dmit) $_{2}$ ] $_{2}$ : from first principles to many-body theory

E. P. Kenny, G. David, N. Ferré +2

We parameterize Hubbard and spin models for EtMe $_{3}$ Sb[Pd(dmit) $_{2}$ ] $_{2}$ from broken symmetry density functional calculations. This gives a scalene triangular model where the large…

Towards mechanomagnetics in elastic crystals: insights from [Cu(acac) $_{2}$ ]

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…
