| Research Abstract |
We have applied pulsed ESR spectroscopy to weakly exchange-coupled molecular bi- and tri-radicals to discuss electron-spin transient nutation (ESTN) phenomena in the spin states. General understandings of the ESTN phenomena in the two or three-spin systems are achieved. It helps us to implement the quantum spin manipulation quantum.
In addition, we have developed electron spin technology by the use of arbitrary wave generators (AWG) in order to precisely manipulate molecular spins. We showed a phase rotation for transient spin nutation experiments using the arbitrary microwaves, indicating that the electron spin state is controlled on the Bloch sphere without any limitations. Hole-burning experiments with coherent-multiple microwave frequencies were also demonstrated. The AWG-based spin technology is applicable to quantum information science/quantum computers as well as high-sensitivity ESR spectroscopy.
