Magnetoelectronic phenomena at a ferromagnet-semiconductor interface

son (HBYJ) describe measurement of the interfacial resistance in a ferromagnet/insulator/semiconductor (F/I/S) structure. They argue that hysteretic features observed between temperatures of 75 and 296 K are evidence for spin-dependent transmission through the interface. We believe that their observations can be attributed to other effects. Despite concerted effort in multiple laboratories, a c...

Polarization at the gold/pentacene interface

Direct and inverse photoemission spectroscopy are used to investigate the electronic polarization P = P + P induced by the pentacene anion and cation at the Au/pentacene interface. Based on the spectroscopic measurements and on previously published calculations, we determine that the total polarization at the metal interface is approximately 0.67 eV larger than at the surface of the pentacene f...

Polarization Phenomena in Electromagnetic Interactions at Intermediate Energies

Recent results of polarization measurements in electromagnetic interactions at intermediate energies are discussed. Prospects of polarization experiments a t the new CW electron accelerators, as well as on upgraded older machines are outlined. I t is concluded that polarization experiments will play a very important role in the study of the structure of the nucleon and of light nuclei.

Chiral-induced polarization at a tilted nematic — substrate interface

An ac electric field at frequency ω is applied to a chiral nematic liquid crystal whose director is tilted by an angle θi with respect to the substrate normal. The nematic director is observed to oscillate at frequency ω azimuthally about the substrate normal, indicating the existence of a component of polarization Pi at the substrate that is perpendicular to the director and parallel to the su...
