We have recently performed a `proof-of-principle' Low Energy Muon Spin Rotation experiment on an organic spin valve. In an extension to our muon measurements and an attempt to gain complementary information about our system, we wish to measure the temperature dependence of the injected spins in an organic spinvalve with spin polarised neutron reflectivity. Using the parameters obtained from our muon measurements, we have calculated the expected spin up/down neutron specular reflectivity, which indicate that these measurements are possible. These extremely topical measurements would yield important information on the spin injection and scattering mechanism in organic molecules. A systematic study of spin transport in organic molecules, as proposed here, will help to push the theoretical understanding of organic spin transport mechanisms to new frontiers.
