Over the last two decades organic spintronics has developed into a strivingfield with exciting reports of long spin diffusion lengths and spin relaxationtimes in organic semiconductors (OSCs). Easily processed and inexpensive, OSCsare considered a potential alternative to inorganic materials for use inspintronic applications. Spin currents have been detected in a wide range ofmaterials, however, there is still uncertainty over the origin of the signals.Recently, we explored spin transport through an organic semiconductor withlateral spin injection and detection architectures, where the injected spincurrent is detected non-locally via spin-to-charge conversion in an inorganicdetector. In this work we show that the widely-used control experiments likelinear power dependence and inversion of the signal with the magnetic field arenot sufficient evidence of spin transport and can lead to an incorrectinterpretation of the signal. Here, we use in-plane angular dependentmeasurements to separate pure spin signal from parasitic effects arising fromspin rectification (SREs). Apart from well established anisotropicmagnetoresistance (AMR) and anomalous Hall effect (AHE), we observed a noveleffect which we call spurious inverse spin Hall effect (ISHE). It stronglyresembles ISHE behaviour, but arises in the ferromagnet rather than thedetector meaning this additional effect has to be considered in future work.
