摘要: The properties of two dimensional frustrated magnets have been studied in an investigation the nuclear magnetism solid3He. results recent heat capacity and NMR measurements on3He films adsorbed on graphite are reported. coverage dependence reveals both antiferromagnetic ferromagnetic regimes their description terms Heisenberg series expansions is discussed. There clear evidence frustration by multiple spin exchange, with no magnetic phase transition. 2D3He currently provides best model system for study S=1/2 quantum antiferromagnetism a triangular lattice. that can be tuned, hence ground state order.
