Abstract
ⶠOhmic contacts and Schottky contacts with rubrene crystals are studied. ⶠNonlinear fits of I:V characteristics with Ni80Fe20 contacts give a barrier height of 0.22(1) eV. ⶠNegative magnetoresistance of 4% is observed in 5 T at 70 K for ohmic Ni80Fe20 contacts. ⶠMagnetoresistance is attributed to weak localization, not a spin valve effect. ⶠSpin diffusion length is less than 200 nm.O
