[en] Lanx was the first manufacturer of vacuum-deposited rigid disks. The technology was based on a Co-Cr perpendicular magnetic recording medium that was compatible with commercially available ferrite ring heads. Performance data for the Lanx perpendicular disk, a description of the manufacturing equipment and some comments on the times are given. - Research highlights: → Lanx was the first manufacturer of sputtered rigid disks. → Lanx Co-Cr perpendicular magnetic recording media worked with existing ring heads. → Linear densities achieved by Lanx and today are similar when geometrically scaled.

[en] To reveal the disadvantages of the traditional technology of facing with chromium-tungsten steels analysis of the given technology was completed. The analysis showed that the main disadvantages of the technology are high-temperature heating and underutilization of high-alloyed metal properties. To eliminate the disadvantages we developed the methods of facing allowing obtaining faced metal which state is close to that of the hardened one without cracks. (paper)

[en] Vaporisation studies over solid and liquid CsI have been carried out by Knudsen effusion (753-897 K) transpiration (862-1125 K) and boiling temperature (977-1430 K) methods. The Knudsen mass loss and transpiration data over CsI(s) are consistent with the presence of monomeric species upto 873 K and the vapour pressure values can be represented by an equation. (orig./RK)

[en] We report on first-principles calculations of spin-dependent quantum transport in a CrAs(0 0 1)/AlAs(0 0 1) heterogeneous junction and predict a strong diode effect of charge and spin current. The minority spin current is absolutely inhibited when the bias voltage is applied to the terminals of both CrAs and AlAs. The majority spin current is inhibited when the bias voltage is applied to the terminal of CrAs and 'relaxed' when the bias voltage is applied to the terminal of AlAs. The charge and spin current diode are promising for reprogrammable logic applications in the field of spintronics
