The invention relates to electrooptical light modulating elements, to electrooptical displays containing elements of this type, and to display systems, e.g. television screens and computer monitors, and to the modulating media used therein. The inventive light modulating elements contain a mesogenic modulating medium that exists in an optically isotropic phase when the light modulating elements are in operation and, in addition to having a good contrast, a low dependency on the viewing angle and very short switching times, they are particularly characterized by having relatively low driving voltages with a very low dependency on temperature. The inventive modulating media are characterized in that they contain a chiral constituent. They preferably also contain an achiral constituent. Especially preferred, the control media comprise a blue phase.

A patterned perpendicular magnetic recording medium has discrete magnetic islands, each of which has a recording layer (RL) structure that comprises two exchange-coupled ferromagnetic layers. The RL structure may be an “exchange-spring” RL structure with an upper ferromagnetic layer (MAG2), sometimes called the exchange-spring layer (ESL), ferromagnetically coupled to a lower ferromagnetic layer (MAG1), sometimes called the media layer (ML). The RL structure may also include a coupling layer (CL) between MAG1 and MAG2 that permits ferromagnetic coupling. The interlayer exchange coupling between MAG1 and MAG2 may be optimized, in part, by adjusting the materials and thickness of the CL. The RL structure may also include a ferromagnetic lateral coupling layer (LCL) that is in contact with at least one of MAG1 and MAG2 for mediating intergranular exchange coupling in the ferromagnetic layer or layers with which it is in contact (MAG2 or MAG1). The ferromagnetic alloy in the LCL has significantly greater intergranular exchange coupling than the ferromagnetic alloy with which it is in contact (MAG2 or MAG1).

Advanced magnetic tunneling junctions (MTJs) that dramatically reduce power consumption (switching energy, E_SW) while maintaining a reasonably high tunneling magnetoresistance (on/off ratio, TMR) and strong thermal stability at room temperature are described herein. The MTJs include a magnetic insulator, such as an antiferromagnetice material, as the tunnel barrier. A more energy efficient switching in the MTJs is achieved by exchange bias switching (EB) due to the magnetoelectric effect (ME) or by magnon assisted switching.
