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…

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…

Spin molecular-orbit coupling and magnetic properties of the decorated honeycomb layers of Mo3S7(dmit)3 crystals

J. Merino, A. C. Jacko, A. L. Khosla +2

We explore the magnetic properties of isolated a-b planes of trinuclear organometallic crystals, Mo3S7(dmit)3, in which an interplay of strong electronic correlations and spin mole…
