Superexchange coupling and spin susceptibility spectral weight in undoped monolayer cuprates

A systematic inelastic neutron scattering study of the superexchange interaction in three different undoped monolayer cuprates (La2CuO4, Nd2CuO4 and Pr2CuO4) has been performed using conventional triple axis technique. We deduce the in-plane antiferromagnetic (AF) superexchange coupling J which actually presents no simple relation versus crystallographic parameters. The absolute spectral weight...

0 Superexchange and lattice distortions in the spin – Peierls system

We present a study of the nearest–neighbor (nn) and next–nearest–neighbor (nnn) exchange constants between magnetic Cu centers of the spin–Peierls material CuGeO 3. The dependence of these constants on the lattice parameters (modified e.g. by variation of temperature, pressure or doping) is calculated. Based on the observation that the bond angles are more susceptible than the bond lengths we p...

Probing superexchange interaction in molecular magnets by spin-flip spectroscopy and microscopy.

The superexchange mechanism in cobalt phthalocyanine (CoPc) thin films was studied by a low temperature scanning tunneling microscope. The CoPc molecules were found to form one-dimensional antiferromagnetic chains in the film. Collective spin excitations in individual molecular chains were measured with spin-flip associated inelastic electron tunneling spectroscopy. By spatially mapping the spi...

Spin Liquid Phase in the Pyrochlore Antiferromagnet

Correlation functions (CFs) of the classical Heisenberg antiferromagnet on the pyrochlore lattice are studied by solving exactly the infinite-component spin-vector model. As in many Fully Frustrated Lattices, the constraint due to the minimization of the energy and the particular structure based on corner sharing tetrahedra both contribute to the creation of local degrees of freedom. The result...

Dynamic scaling in the susceptibility of the spin-1/2 kagome lattice antiferromagnet herbertsmithite.

The spin-1/2 kagome lattice antiferromagnet herbertsmithite, ZnCu(3)(OH)(6)Cl(2), is a candidate material for a quantum spin liquid ground state. We show that the magnetic response of this material displays an unusual scaling relation in both the bulk ac susceptibility and the low energy dynamic susceptibility as measured by inelastic neutron scattering. The quantity chiT(alpha) with alpha appr...
