TLDR
A review of major advances in organic spin valve research can be found in this paper, where the underlying physics in spin injection and transport, high temperature operations, and functionality are discussed.Abstract:
Organic spintronics is an emerging and potential platform for future electronic devices. Significant progress has been made in understanding the spin injection, manipulation, and detection in organic spin valves in the past decade plus since its discovery. Studies have also been advanced to a range of materials combination of organic semiconductors and ferromagnetic electrodes for improving their performance especially at high temperatures. In addition, there are several remarkable studies on development of the spin valves as a multifunctional device. However, the research in this field is still in its infancy and there is a need to resolve many issues which keep this field far away from applications. In this report, we review major advances in organic spin valves such as understanding the underlying physics in spin injection and transport, high temperature operations, and functionality. We also highlight some of the outstanding challenges in this promising research field. Finally, we suggest an outlook on the future of organic spintronics.read more

Spin Injection and Relaxation in Ferromagnet-Semiconductor Heterostructures
TL;DR: In this paper, a detailed description of spin injection and detection in semiconductor heterostructures for temperatures from 2 to 295 K was presented, and the spin injection efficiency of the Schottky barrier decreases at higher temperatures, although a steady state spin polarization of at least 6% is observed at 295 K.

Enhanced Magnetoresistance in Chiral Molecular Junctions.
TL;DR: It is found that the α-helix conformation displays a spin polarization, calculated through the intrinsic magneto-resistance of the junction, about 100-1000 times larger than the linear β-strand, clearly demonstrating the crucial role played by the molecular helical geometry on the enhancement of spin polarization associated with the CISS effect.
