Journal ArticleDOI
Isotope effect in spin response of pi-conjugated polymer films and devices.
Tho Duc Nguyen,Golda Hukic-Markosian,Fujian Wang,Leonard Wojcik,Xiaoguang Li,Eitan Ehrenfreund,Z. Valy Vardeny +6 more
TL;DR: It is demonstrated that the HFI does indeed have a crucial role in all three spin responses and OLED films based on the D-polymers show substantially narrower magneto-electroluminescence and ODMR responses, and OSV devices based on D- polymers show a substantially larger magnetoresistance.
Journal ArticleDOI
Organic-based magnon spintronics
Haoliang Liu,Chuang Zhang,Hans Malissa,Matthew Groesbeck,Marzieh Kavand,Ryan McLaughlin,Shirin Jamali,Jingjun Hao,Dali Sun,Royce A. Davidson,Leonard Wojcik,Joel S. Miller,Christoph Boehme,Z. Valy Vardeny +13 more
TL;DR: Generation, transport and detection of spin-wave quanta in vanadium tetracyanoethylene, an organic ferrimagnet with low Gilbert damping, are reported.
Journal ArticleDOI
The hyperfine interaction role in the spin response of π-conjugated polymer films and spin valve devices
Tho Duc Nguyen,Golda Hukic-Markosian,Fujian Wang,Leonard Wojcik,Xiaoguang Li,Eitan Ehrenfreund,Eitan Ehrenfreund,Z. Valy Vardeny +7 more
TL;DR: In this paper, the spin dynamics in films and organic spin-valve (OSV) devices based on π-conjugated polymers made of protonated, H-, deuterated, D-hydrogen and 13 C-rich chains were compared.
Patent
Device Comprising Deuterated Organic Interlayer
TL;DR: In this paper, an organic interlayer comprising a deuterated organic material was proposed to manipulate or control a magnetic field, such as a spin-valve device, an organic light-emitting device, a compass or a magnetometer.
Patent
π-conjugated heavy-metal polymers for organic white-light-emitting diodes
TL;DR: In this paper, a spin-orbit coupling mechanism was used to cause the ratio of fluorescent to phosphorescent light emission bands to be of approximately equal strength, resulting in an emission spectrum that appears to the eye to be white.
