Title

Spin-wave dispersion in the 2D square lattice of a metal-organic framework

Abstract

The metal-organic compound [Cu(H2O)2(C4H4N2)2]Cr2O7 forms a 2D magnetic square lattice in the bc-plane. It doesn't show any long-range order down to a few mK, due to a very weak interlayer coupling. Still, our preliminary measurements on PANDA revealed spin wave excitations of the square lattice. Here, we propose to investigate its spin dynamics by means of three-axis spectrometry. This shall enable us to study the Hamiltonian and relate it to the magnetic properties allowing an understanding of its ground state. The final goal will be then to tune the dimensionality of the system towards 1D by application of external pressure on a follow-up future experiment. We expect this to shed light on the transformation between 2D-1D.
