Unusual suppression of superconductivity in YNi2B2C under neutron irradiation
A. E. Karkin, Yu. N. Akshentsev, B. N. Goshchitskii
The behavior of electrical resistivity rho(T), temperature of superconducting transition Tc, and upper critical field Hc2(T) of polycrystalline YNi2B2C after irradiation with therm…
Superconductivity in iron silicide Lu2Fe3Si5 probed by radiation-induced disordering
A. E. Karkin, M. R. Yangirov, Yu. N. Akshentsev +1
Resistivity r(T), Hall coefficient RH(T), superconducting temperature Tc, and the slope of the upper critical field -dHc2/dT were studied in poly- and single-crystalline samples of…
Synthesis, crystal growth and superconducting properties of Fe-Se system
A. E. Karkin, A. N. Titov, E. G. Galieva +2
Single crystals FeSex were grown in an evacuated sealed quartz tube using polycrystalline material by gas-transport reaction with I2 as a gas-carrier. Crystals with hexagonal-prism…
Neutron-irradiation effects in LaO0.9F0.1FeAs superconductor
A. E. Karkin, J. Werner, G. Behr +1
The effect of atomic disorder induced by neutrons irradiation on superconducting and normal state properties of polycrystalline LaFeAsO_0.9F_0.1 was investigated. The irradiation o…
New enlargement of the novel class of superconductors
V. L. Kozhevnikov, O. N. Leonidova, A. L. Ivanovskii +3
Here we report on synthesis and characterization of a new member LaO1-deltaNiBi in the family of novel superconductors. Though the onset superconducting temperature ~4 K is smaller…
Point-contact spectroscopy of the normal state excitations in PrOs4Sb12
O. E. Kvitnitskaya, Yu. G. Naidyuk, I. K. Yanson +3
Point-contact (PC) investigations of the heavy-fermion (HF) superconductor PrOs4Sb12 in the temperature range between 1.5 and 4.2K and in a magnetic field up to 8T are presented. T…
