Real-time estimation of the optically detected magnetic resonance shift in diamond quantum thermometry

Masazumi Fujiwara, Alexander Dohms, Ken Suto +6

We investigate the real-time estimation protocols for the frequency shift of optically detected magnetic resonance (ODMR) of nitrogen-vacancy (NV) centers in nanodiamonds (NDs). Ef…

Pure spin current in a robust pigment-red film

Kazuhiro Nishida, Yoshio Teki, Eiji Shikoh

We report the spin current properties in a pigment-red (perylene-3,4,9,10-tetracarboxylic dianhydride: PTCDA) film prepared by thermal evaporation. In a palladium(Pd)/PTCDA/Ni80Fe2…
