Project summaryAmong various magnetooptic (MO) materials known up to date the most promisible are epitaxial (epi) films 9f Bi-substituted iron garnets grown on nonmagnetic substrates. Combination of magnetic and optical properties has drawn to these materials a pronounced interest either of defense or civilian specialists.
The main objectives of the present project include:
- substational improvement of sensitivity and fast action of Bi-substituted epi films;
- realization of numerous promising civilian devices on the base of new MO materials.
The approach to developing of most of new MO devices is based on original MO method for ingomogeneous magnetis field visualization and mapping.
The spectra of MO devices Includes the following:
- High reliable MO bank-note tester for operative definition of authenticity of bills (bank note) and securities. This application already confirmed its great commercial value all over the world.
- Set of devices for latent marking of arbitrary articles, intended for protection of goods and their components against forgery, adulteration, where invisible imprint can be read using special MO lens. Seems to be of serious commercial interest both for home and foreign security and insurance services.
- MO flaw detectors for real time defect revealing in both magnetic and nemagnetic metal articles. Seems to be of great commercial interest for FSU and US in particular for aircraft industry.
- High resolution localozator of magnetic axis for multiple magnets in nuclear accelators and colliders. This application is civilian prolongation of our previous works on nuclear beam weapons.
- MO nonmechanical high speed system for precise light beam scanning and addressing. This application is civilian prolongation of our previous works on satellite watching and orientation systems.
All above-mentioned devices are already realized in the form of working models or experimental patterns, which caused pronounced interest or potential customers.
However sufficient improvements of the devices are necessary to meet the customer’s requirements, for which the ISTC financial support is needed. This in particular concerns the device automation and computer processing of magnetic patterns.
The other direction of required ISTC financial support concerns improvement of MO material, in particular their sensitivity, fast action, spatial resolution. In this field the authors of the project have developed original ideas, concerning new epitaxial regimes, compositions, physical mechanisms of remagnetization.
The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.
ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
