Cyclotron resonance (CR) of high mobility 2D electron systems (2DEG) in the extreme quantum limit has been studied. Below a critical filling factor (vc≈1/10) an additional CR line is observed at the high energy side of the conventional CR. The temperature behaviour of the two CR absorptions can be described within a two level model. A total condensation into the novel state occurs at temperatures below 1K. The new phase can be interpreted as a magnetically induced Wigner crystal.
