Abstract

The magnetic properties of the 2DES close to ν = 1 are studied by the direct measurement of the low-lying spin excitation spectrum by inelastic light scattering at sub-Kelvin temperatures. The results suggest an instability of the two-dimensional electron systems (2DES) toward magnetic order at low temperatures. The spin excitation spectra are consistent with the ordering of the in-plane components of spin in a square crystal phase proposed in theoretical evaluations. Our experiments create venues for the determination of spin phases from measurements of low-lying spin excitations by inelastic light scattering.
