 The study reports an unusual magnetoresistance, Mr. bias dependence in La underscore 0.7 senior underscore 0.3 MnO underscore 3, Lsmo, Alk underscore 3, co-organic spin valve, Osv, with a tunnel barrier between Lsmo and Alk underscore 3, where the inverse Mr. peaks at negative bias and sine reversal occurs at positive bias. In contrast to commonly found inverse Mr. in entire bias range for Lsmo, Alk underscore 3, co-Osv. The Mr. bias voltage dependence is independent on the type of tunnel barrier, either SRTO underscore 3 or RL underscore 2, O underscore 3. First principle calculations demonstrate that the strongly hybridized co-D states with Alk underscore 3 molecules at the interface are responsible for efficient D state spin injection and the observed Mr. bias dependence is originated from energy dependent density of states of co-D states. This finding opens up new possibilities to engineer interfacial bonding between ferromagnetic materials and a wide variety of molecule selections for desired spin transport properties.
