Large Skyrmions in an Al(0.13)Ga(0.87)As Quantum Well
S. P. Shukla, M. Shayegan, S. R. Parihar +3
We report tilted-field magnetotransport measurements of two-dimensional electron systems in a 200 Angstrom-wide Al(0.13)Ga(0.87)As quantum well. We extract the energy gap for the q…

Magnetic Anisotropy in Quantum Hall Ferromagnets
T. Jungwirth, S. P. Shukla, L. Smrcka +2
We show that the sign of magnetic anisotropy energy in quantum Hall ferromagnets is determined by a competition between electrostatic and exchange energies. Easy-axis ferromagnets…
