Abstract:We studied neutral excitations in a two-dimensional electron system with an orbital momentum ∆M = 1 and spin projection over magnetic field axis ∆S z = 1 in the vicinity of a filling factor of 3/2. It is shown that the 3/2 state is a singular point in the filling factor dependence of the spin ordering of the two-dimensional electron system. In the vicinity of ν = 3/2, a significant increase in the relaxation time (τ = 13 µs) for the excitations to the ground state is exhibited even though the number of vacanci… Show more
