Memory magneto-optical

These effects open up the possibility of novel magneto-optical memory devices. 

The excellent insulating and dielectric properties of BN combined with the high thermal conductivity make this material suitable for a huge variety of applications in the electronic industry [142]. BN is used as substrate for semiconductor parts, as windows in microwave apparatus, as insulator layers for MISFET semiconductors, for optical and magneto-optical recording media, and for optical disc memories. BN is often used as a boron dopant source for semiconductors. Electrochemical applications include the use as a carrier material for catalysts in fuel cells, electrodes in molten salt fuel cells, seals in batteries, and BN coated membranes in electrolysis cells for manufacture of rare earth metals [143-145]. 

In a similar way, the video disk reconverts the signal produced by the Kerr effect on a thin film of an amorphous substance such as Tb-Fe sputtered on a substrate disk made of plastic or glass. The Tb-Fe film functions like a perpendicular magneto-optical memory... 

As described above, write-once optical disks (CD-R and DVD-R) using organic molecular materials are now commercially available. The next target is to develop erasable memory media. At present inorganic materials, such as magneto-optic or...

The magneto-optical properties of the compound MnBi were extensively studied by many authors in connection with the possibility of using this material in the form of thin films in magneto-optical memory systems. A more detailed description of these... 

Among the numerous materials proposed for applications in magneto-optical memories, thin films of MnBi were most intensively studied. In the present section the attention will be focussed mainly on the magneto-optical properties and related... 

Consequently, the construction of spin transition ID, 2D or 3D coordination polymers has attracted attention in recent years, and may form the base in new devices for memory, display and other magneto-optical applications [71-79],... 

During the past 15 years the Eu chalcogenides have received tremendous interest by scientists all over the world. One obvious reason was the hope of using these magnetic semiconductors industrially, e.g. in the form of fast, light beam addressable memory systems in computers, as magneto-optical modulators or as magnetic field activated electronic switches. 

Perovskite materials have many interesting and spectacular properties such as high temperature superconductors, magneto resistance, ferroelectricity, charge ordering, spin dependent transport, high thermo power, optical properties, etc. As well as their applications in catalyst electrodes in certain types of fuel cells, memory devices, etc.
