Superconductivity in La1.85Sr0.15CuO4 Ceramic Samples
N. V. Dalakova, B. I. Belevtsev, E. Yu. Beliayev +4
Effects related to the granularity of a La1.85Sr0.15CuO4 ceramic sample, synthesized by the solidstate reaction method, are presented. The superconducting transition exhibits a ste…
Features of Low Temperature Tunnel Magnetoresistance in Pressed Powder of Chromium Dioxide
V. A. Horielyi, N. V. Dalakova, E. Yu. Beliayev
Resistive and magnetoresistive properties of two samples of compacted powders of ferromagnetic half-metal CrO_{2} with shape anisotropy of nanoparticles were studied. The powders w…
Suppression of antiferromagnetic order in low-dopped ceramic samples La_{2-x}Sr_{x}CuO_{4}
N. V. Dalakova, B. I. Belevtsev, E. Yu. Beliayev +2
Possible influence of spatially inhomogeneous distribution of strontium impurities on the temperature of antiferromagnetic (AFM) ordering in ceramic samples La2-xSrxCuO4 has been r…
Resistive and magnetoresistive properties of CrO2 pressed powders with different types of inter-granular dielectric layers
N. V. Dalakova, B. I. Belevtsev, E. Yu. Beliayev +4
Resistive, magnetoresistive and magnetic properties of four kinds of pressed CrO2 powders, synthesized by hydrothermal method of chromic anhydride have been investigated. The parti…
Transport and magnetotransport properties of cold-pressed CrO powder, prepared by hydrothermal synthesis
B. I. Belevtsev, N. V. Dalakova, M. G. Osmolowsky +2
Submicron powder of CrO was prepared by hydrothermal synthesis method from chromium trioxide. Particles obtained were of rounded form with mean diameter about 120 nm. The powde…
The effect of magnetic (phase) inhomogeneities upon the low temperature conductivity of antiferromagnetic La_{2}CuO_{4+δ} single crystal
N. V. Dalakova, B. I. Belevtsev, E. Yu. Beliayev +3
It is found that a strong inhomogeneous distribution of oxygen in single crystal La_{2}CuO_{4+δ} can lead to the formation of isolated superconducting inclusions, the average hole…
