Abstract Recently, several multifunctional organic spin valves (OSVs) integrating both magnetoresistance (MR) effect and nonvolatile memory effect were reported. In most cases, single unmodified organic layers were employed, and the underlying mechanism of the memory effect was not fully understood. Here, we present a simple and effective method to achieve nonvolatile memory in OSVs by doping the organic interlayer of the sandwich device, which will introduce traps in the organic interlayer and affect charge and spin transport. The doped OSVs exhibit a current-voltage hysteresis and reversible resistive switching behavior, indicating that the nonvolatile memory is achieved. The trap-controlled space-charge-limited current model can explain the memory effect of the doped OSVs, and combined with spin diffusion theory based on hyperfine interaction it can also explain the corresponding MR changes under different resistance states.
