Abstract
We report integration of organic photodetector and organic spin valve in a single physical device – ITO/V[TCNE]2/rubrene/Co/Au magnetic organic photodetector heterostructure. Generation of photocurrent with more than 43.3% photocurrent to dark current ratio is revealed in this device under illumination of 660 nm red laser light at 0.4 V electrical bias. Moreover, room temperature spin valve response with up to 7.7% spin valve magnetoresistance peak is found at 138 Oe in the same heterostructure. Such intriguing coexistence of photocurrent generation and spin valve effect at room temperature in a single magnetic organic photodetector heterostructure paves the way for development of eco‐friendly all‐organic next generation multifunctional opto‐spintronics devices.This article is protected by copyright.

期刊介绍：
Physica status solidi (RRL) - Rapid Research Letters was designed to offer extremely fast publication times and is currently one of the fastest double peer-reviewed publication media in solid state and materials physics. Average times are 11 days from submission to first editorial decision, and 12 days from acceptance to online publication. It communicates important findings with a high degree of novelty and need for express publication, as well as other results of immediate interest to the solid-state physics and materials science community. Published Letters require approval by at least two independent reviewers.
The journal covers topics such as preparation, structure and simulation of advanced materials, theoretical and experimental investigations of the atomistic and electronic structure, optical, magnetic, superconducting, ferroelectric and other properties of solids, nanostructures and low-dimensional systems as well as device applications. Rapid Research Letters particularly invites papers from interdisciplinary and emerging new areas of research.
