Uncoupled surface spin induced exchange bias in α-MnO(2) nanowires

We have studied the microstructure, surface states, valence fluctuations, magnetic properties, and exchange bias effect in MnO(2) nanowires. High purity α-MnO(2) rectangular nanowires were synthesized by a facile hydrothermal method with microwave-assisted procedures. The microstructure analysis ind...
