Evidence for Skyrmions and Single Spin Flips in the Integer Quantized Hall Effect
Evidence for Skyrmions and Single Spin Flips in the Integer Quantized Hall Effect
We have employed tilted-field magneto-transport measurements of the energy gap for the odd-integer quantized Hall states at Landau level filling factors $\nu = 1$,3 and 5 to determine the spin of thermally excited quasielectron-quasihole pairs. At $\nu = 1$ our data show that as many as 7 electron spin flips …
