We paid several visits to MGU and as a result 6 common papers were published, mostly in prestigious physical journals.
Unfortunately, in early period only coworkers of respective Academies of Sciences had an access.
Obviously, the cooperation is at present extended to new multicomponent materials including hydrides and new phenomena as new superconductivity, strongly correlated electrons and magnetocaloric effect.
For these materials magnetization in high pulsed magnetic fields, the magnetostriction and electrcal properties were determined.
The investigated ternaries or pseudoternaries were most frequently in the single crystal form exhibiting the following crystal structure very common for hard magnetic materials: with the Th2Ni17 and ThMn12 crystal types and the compounds with 1:1:1 stoichiometry, with the orthorhombic TiNiSi or the tetragonal CeFeSi structure types.

It is very important to reconstruct the damaged roads as soon as possible in order to send the external aids and relief aid materials to earthquake-hit areas and transport the disaster victims to hospital in a short time after earthquake.
Many people put up the tents on the sidewalk and road shoulder, many goods and materials were piled up along the roadside.
