Proton Spin Relaxation Induced by Quantum Tunneling in Fe8 Molecular Nanomagnet

Miki Ueda, Satoru Maegawa, Susumu Kitagawa

The spin-lattice relaxation rate $T_1^{-1}$ and NMR spectra of ${}^1$H in single crystal molecular magnets of Fe8 have been measured down to 15 mK. The relaxation rate $T_1^{-1}$ s…
