▼ [6a-C18-9] Research on spin pumping into p-type diamond
キーワード:diamond, spin-pumping
We focus on a spin-pumping technique to demonstrate spin-injection into diamond because the spin-polarized electron may be used for electrical initialization of electron spins in NV centers. This study observed electromotive forces in detectors of Pd and Ta under FMR of aNiFe layer. The results show the signs of inverse spin-Hall voltages in Pd and Ta were opposite. This fact strongly suggests demonstration of spin-injection into diamond by the spin-pumping.
