| Research Abstract |
Localized Magnetic Moment (LMM) and the controlling of the spin state have been studied in the coupled Quantum Point Contacts (QPCs). The direct observation for the spin related electron-wave dynamics, can be realized in the QPCs sample prepared by micro-fabrication in semiconductors or nano-carbon materials by use of the low-temperature magneto-resistances under the microwave or terahertz wave radiation and the scanning gate modulation.
