Multiple transitions of the spin configuration in quantum dots
arXiv:cond-mat/0606414 · doi:10.1103/PhysRevLett.97.176801
Abstract
Single electron tunneling is studied in a many electron quantum dot in high magnetic fields. For such a system multiple transitions of the spin configuration are theoretically predicted. With a combination of spin blockade and Kondo effect we are able to detect five regions with different spin configurations. Transitions are induced with changing electron numbers.
