Optical and magnetic properties of the ground state of Cr doping ions in REM(BO) single crystals.

New data about the state of Cr doping ions in a single crystal of YGa(BO) have been obtained by studying different methods. Using electron paramagnetic resonance, it was found that the Cr ions substitute the trivalent gallium ions. The obtained spin Hamiltonian parameters of the Cr ions in the YGa(BO) single crystal (g = 1.

Self-assembly in aqueous solutions of imidazolium ionic liquids and their mixtures with an anionic surfactant.

Experimental data on micellization in aqueous solutions of 1-alkyl-3-methylimidazolium salts [C(n)mim]X and their mixtures with sodium dodecyl sulfate (NaDS) are reviewed. New results (the critical micelle concentration and enthalpy of micellization) are presented for mixtures of [C(4)mim]PF(6), [C(6)mim]BF(4), [C(6)mim]Br and [C(10)mim]Br with NaDS. Our data cover a wide range (from 0 to 0.
