Organic ferroelectric Croconic Acid: A concise survey from bulk single crystals to thin films
Sambit Mohapatra, Salia Cherifi-Hertel, Senthil Kumar Kuppusamy +7
Owing to prospective energy-efficient and environmentally benign applications, organic ferroelectric materials are useful and necessary alternative to inorganic ferroelectrics. Alt…
Thickness-dependent electron momentum relaxation times in iron films
K. L. Krewer, W. Zhang, J. Arabski +4
Terahertz time-domain conductivity measurements in 2 to 100 nm thick iron films resolve the femtosecond time delay between applied electric fields and resulting currents. This curr…
Robust ferroelectric properties of organic Croconic Acid films grown on spintronically relevant substrates
Sambit Mohapatra, Victor Da Costa, Garen Avedissian +4
The discovery of stable room temperature ferroelectricity in Croconic Acid, an organic ferroelectric material, with polarization values on par with those found in inorganic ferroel…
Thickness-dependent electron momentum relaxation times in thin iron films
Keno L. Krewer, Wentao Zhang, Jacek Arabski +4
Terahertz time-domain conductivity measurements in 2 to 100 nm thick iron films resolve the femtosecond time delay between applied electric fields and resulting currents. This resp…
Disentangling magnetic hardening and molecular spin chain contributions to exchange bias in ferromagnet/molecule bilayers
Samy Boukari, Hashim Jabbar, Filip Schleicher +9
We performed SQUID and FMR magnetometry experiments to clarify the relationship between two reported magnetic exchange effects arising from interfacial spin-polarized charge transf…
Cu metal / Mn phthalocyanine organic spinterfaces atop Co with high spin polarization at room temperature
E. Urbain, F. Ibrahim, M. Studniarek +14
The organic spinterface describes the spin-polarized properties that develop, due to charge transfer, at the interface between a ferromagnetic metal (FM) and the molecules of an or…
Efficient, high-density, carbon-based spinterfaces
F. Djeghloul, G. Garreau, M. Gruber +14
The research field of spintronics has sought, over the past 25 years and through several materials science tracks, a source of highly spin-polarized current at room temperature. Or…
Direct observation of a highly spin-polarized organic spinterface at room temperature
F. Djeghloul, F. Ibrahim, M. Cantoni +23
The design of large-scale electronic circuits that are entirely spintronics-driven requires a current source that is highly spin-polarised at and beyond room temperature, cheap to…
Control of defect-mediated tunneling barrier heights in ultrathin MgO films
D. J. Kim, W. S. Choi, F. Schleicher +9
The impact of oxygen vacancies on local tunneling properties across rf-sputtered MgO thin films was investigated by optical absorption spectroscopy and conducting atomic force micr…
Random barrier double-well model for resistive switching in tunnel barriers
Eric Bertin, David Halley, Yves Henry +6
The resistive switching phenomenon in MgO-based tunnel junctions is attributed to the effect of charged defects inside the barrier. The presence of electron traps in the MgO barrie…
Study of molecular spin-crossover complex Fe(phen)2(NCS)2 thin films
Shengwei Shi, G. Schmerber, J. Arabski +12
We report on the growth by evaporation under high vacuum of high-quality thin films of Fe(phen)2(NCS)2 (phen=1,10-phenanthroline) that maintain the expected electronic structure do…
