Authors
Abstract:
The growth processes of Tetragonal single crystals of solid solution (Cd0.6Zn0.32Mn0.08)3As2, space group P42/nmc, has been synthesized by Bridgman method. Conductivity and magnetoresistance of (Cd0.6Zn0.32Mn0.08)3As2 were measured in the range 1.6K to 300K and in magnetic field up to 25 T. Crossover from Mott variable-range-hopping conductivity mechanism close to helium temperatures. In this work, we found the width of the coulomb D = 0.21 meV and a rigid gap δ = 0.026 meV in the density of localized states, concentration and localization radius of charge carriers.

Single Array and Bound Method (RESEARCH NOTE).
One of the major disadvantages of using Branch and Bound algorithm to solve permutation bases problems by computer is the size of main memory required. The single Array Branch and Bound (SABB) method introduction here aims to overcome this deficiency, using only N memory locations as a vector of size N, and a single cell C with N bits.

Electrical conductivity measurements are reported for normal and deuterated ammonium chloride single crystals in the temperature regions which characterize the pure and the impurity-dominated materials. We conclude from the data that conductivity in ammonium chloride is due to the formation of either cation or anion vacancies and a subsequent process controlled by a proton transfer. Our results...

Resistivity, ρ (T), of LaMnO3+δ displays between δ = 0 − 0.154 an activated behavior both above and below the paramagnetic (PM) to ferromagnetic transition temperature, TC. The relative magnetoresistance at 8 T reaches the values of – 88 % near TC and – 98 % at T ≈ 20 K. In the PM phase ρ (T) satisfies between TC ~130 − 160 K and Tv ∼ 250 − 270 K the Shklovskii – Efros-like variable-range hoppi...

We have measured the a. c. conductivity of pure BaFz single crystals up to 1 336 K. At the higher temperatures we observed polarisation effects possibly due to a reaction of the crystal with the atmosphere in the cell. The defect energies derived from the low temperature region agree well with those obtained by Barsis and Taylor [27, 281. The effect of the high temperature phase transition on t...
