Magnetization curve of second layer antiferromagnetic solid 3He on graphite in high magnetic fields
نویسندگان
چکیده
Two dimensional anti-ferromagnetic solid He adsorbed on graphite, so called 4/7 phase, is a strongly frustrated quantum spin system and the ground state is considered to be a gapless spin liquid. To clarify the magnetic behavior, the magnetization curve has been investigated below 1 mK in high magnetic fields, using NMR over the wide frequency region up to 360 MHz. The magnetization is found to reach full saturation at around 10 T.

We apply exact high-temperature series expansions of the multiple-spin-exchange Hamiltonian for a triangular lattice to describe high precision NMR measurements of the nuclear magnetic susceptibility of 3He films adsorbed on graphite, reported here, as well as all available specific heat data. A consistent quantitative description of the unusual thermodynamic properties of the second layer soli...
متن کاملOnset of ferromagnetic exchange in adsorbed 3He films.
Nuclear magnetic resonance experiments are reported on multilayer He films adsorbed on the surface of graphite. Initially the second layer exhibits antiferromagnetic exchange, which has been measured as a function of coverage. Measurements of the nuclear magnetic susceptibility and resonant frequency for coverages around the third layer promotion precisely identify the onset of ferromagnetic ex...
متن کاملWhat is Minimal Model of 3 He Adsorbed on Graphite ? – Importance of Density Fluctuations in 4 / 7 Registered Solid –
We show theoretically that the second layer of He adsorbed on graphite and solidified at 4/7 of the first-layer density is close to the fluid-solid boundary with substantial density fluctuations on the third layer. The solid shows a translational symmetry breaking as in charge-ordered insulators of electronic systems. We construct a minimal model beyond the multiple-exchange Heisenberg model. A...
