(a) Fullerence thickness dependence of MR at 120 K.
The black and red open dots are measured MR of LSMO(50 nm)/C60/Co(15 nm) and LSMO(50 nm)/C70/Co(15 nm) OSVs, respectively. All MRs were taken at the junction voltage of −20 mV. The lines were fitted based on Eq. 1. (b) Temperature dependence of spin diffusion length, LS, of C70- and C60-based OSVs. The spin polarization, |P1·P2|, of (c) C70- and (d) C60-based OSVs. The insets show the normalized |P1·P2| and LSMO magnetization versus temperature. The bars show errors of the measurement and fittings.
