Opis:: The ECR laboratory of the Cyclotron Centrum of Slovak Republic (CC SR) in Bratislava, Slovakia, consists of the DECRIS 14-2m ion source and two low energy channels. It is a complete injector, consisting of an ECR ion source, focusing and steering elements, an analyzing magnet, a vacuum system, and an ion beam diagnostic system. The DECRIS 14-2m ion source is a multiply charged heavy ion source based on the electron cyclotron resonance principle. The ECR ion source DECRIS 14-2m and other system have been designed and manufactured at the FLNR JINR. The preliminary testing (magnetic field measurements, vacuum testing and testing of ECR ion source) has been performed at FLNR JINR. The final assembly of the DECRIS 14-2m will be done at the CC SR in Bratislava.

Opis:: Porous synthetic opal possessing a three-dimensional photonic band structure of semimetallic type was impregnated with polycrystalline CdS. The photonic stop band in (111) direction was examined by means of photoreflection technique. Under cw laser excitation of semiconductor inclusions the reflectance of the system changes indicating a modification of photonic band structure. A possible mechanism is discussed. Numerical simulations within the framework of quasicrystalline approximation are given.

Opis:: High precision measurements of magnetoresistance Δρ/ρ = f(T,H) and magnetization M(T,H) were carried out on single crystals of rare-earth dodecaboride $ErB_{12}$ at temperatures in the interval 1.8-30 K in magnetic fields up to 70 kOe. The high accuracy of the experiments allowed us to perform numerical differentiation and analyze quantitatively the behavior of the derivative d(Δρ/ρ)/dH = f(T,H) and of the magnetic susceptibility χ(T,H) = dM/dH in paramagnetic and magnetically ordered (antiferromagnetic, $T_N$ ≈ 6.7 K and $T_M$ ≈ 5.85 K) phases of $ErB_{12}$. It was shown that negative magnetoresistance anomalies observed in present study in paramagnetic state of $ErB_{12}$ may be consistently interpreted in the framework of a simple relation between resistivity and magnetization -Δρ/ρ ~ $M^2$.
