Trans-polyacetylene based organic spin valve for a multifunctional spin-based device: A first principle analysis

Electrically programmable magnetoresistance in multifunctional organic-based spin valve devices.

Information and communication technology (ICT) is now calling for solutions enabling lower power consumption, further miniaturization, and multifunctionality requiring the development of new device concepts and new materials. [ 1 ] One of the most fertile approaches to meet such demands is spintronics, which is now facing the challenge of evolving from the fi rst generation of devices that led ...

Electrically controllable magnetoresistance switching in multifunctional organic based spin-valve devices

LSMO Low Resistance High resistance The Fig.4a shows the spin valve presented previously in Fig.1 before any higher voltage was applied this corresponds to the lowest resistance state and a SVMR of 22%. Next, we apply a voltage bias of -1.5 V and the device resistance increases from 362 kOhms to 4.3 MOhms. The voltage is subsequently reduced back to the measuring value of -0.1 V and the magneto...

Spin-polarized light-emitting diode based on an organic bipolar spin valve.

The spin-polarized organic light-emitting diode (spin-OLED) has been a long-sought device within the field of organic spintronics. We designed, fabricated, and studied a spin-OLED with ferromagnetic electrodes that acts as a bipolar organic spin valve (OSV), based on a deuterated derivative of poly(phenylene-vinylene) with small hyperfine interaction. In the double-injection limit, the device s...

Nuclear spin-lattice relaxation in trans-polyacetylene (CH)x. A confined soliton model including nuclear spin flip diffusion

2014 A « confined soliton model » in which the solitons move over a small part of the chain is developed. The on-chain nuclei are relaxed directly by contact hyperfine interactions whilst the remainder nuclei relax via nuclear spin flip diffusion. It is found that the proton spin-lattice relaxation data can be rationalized in terms of the fast and confined one-dimensional hopping motion of the ...
