When different Landau-levels (LLs) with different spin characteristics cross each other, electron interaction plays an essential role and unique characteristics like quantum Hall ferromagnet appear. Although many interesting physics have been found at many different LL crossings, I concentrate two LL crossings observed for compound semiconductor two-dimensional (2D) systems here.

Finally, I will discuss electron spins / nuclear spins interaction at the crossing and resistively detected NMR in InSb 2D system [3].
