Wigner solids of domain wall skyrmions

Kaifeng Yang, Katsumi Nagase, Yoshiro Hirayama +3

Detection and characterization of a different type of topological excitations, namely the domain wall (DW) skyrmion, has received increasing attention because the DW is ubiquitous…

Nonlinear magnetic field dependence of spin polarization in high density two-dimensional electron systems

K. F. Yang, H. W. Liu, T. D. Mishima +3

The spin polarization (P) of high-density InSb two-dimensional electron systems (2DESs) has been measured using both parallel and tilted magnetic fields. P is found to exhibit a su…
