The influence of both photochromic doping and photochromic transitions on the effect of magnetooptical rotation (Farady effect FE) of undoped and doped with Cr, Mn and Cu Bi 12 SiO 20 (BSO) and Bi 12 TiO 20 (BTO) crystals is studied. The present results show, that Cr, Mn and Cu increase the FE. The influence of Cr, whose affect on the optical activity (OA) of BSO is most significant, here is to...

We produce Bose-Einstein condensates of 6Li2 molecules in a low power (22W) crossed optical dipole trap. Fermionic Li atoms are collected in a magnetooptical trap from a Zeeman slowed atomic beam, then loaded into the optical dipole trap where they are evaporatively cooled to quantum degeneracy. Our simplified system offers a high degree of flexibility in trapping geometry for studying ultracol...

The effects of the precursor milling energy on the superconducting and microstructural homogeneity of Fe-sheathed MgB2 monocore wires and tapes have been investigated. The conductors were produced by the powder-in-tube method using drawing and rolling deformation methods and in situ reaction. Combined magnetooptical, structural and magnetization measurements were performed on MgB2 superconducti...
