We report the structural and transport properties of LaNiO3 thin films prepared by pulsed laser deposition technique. To understand the effects of film thickness, lattice mismatch and grain size on transport properties, various oriented substrates we

The anomalous low-temperature behaviour of the spontaneous magnetization of ordered arrays of quantum dots is discussed. It is shown that the experimental results can be well understood, within a mean field approximation, assuming collective response

We discuss the origin of the temperature dependence of resistivity ρ observed in highly oriented LaNiO3 thin films grown on SrTiO3 substrate by a pulsed laser deposition technique. All the experimental data are found to collapse into a single univer

By improving resolution of home-made mutual-inductance measurements technique, a pronounced step-like structure (with the number of steps n=4 for all AC fields) has been observed in the temperature dependence of AC susceptibility in artificially prep

Approximating the shape of the measured in $Bi_2Sr_2CaCu_2O_y$ magneto-thermopower (TEP) $\Delta S(T,H)$ by asymmetric linear triangle of the form $\Delta S(T,H)\simeq S_p(H)\pm B^{\pm}(H)(T_c-T)$ with positive $B ^{-}(H)$ and $B ^{+}(H)$ defined bel

A method, using a Corbino disk sample geometry, is described and applied to study of resistive tails of sintered $YBCO$. When the transport current passes radially from the rim of the disk sample to its center, the two component potential drop signal

Experimental data for the normal state Hall number density, nH varies as a+bT, in (pure and low-level Zn-doped) rather well oxygenated YBCO high-Tc superconductors show an anomalous change of slope ('back bending') above some temperature T0 which var

The ac susceptibilities of YBa[sub 2](Cu[sub 1[minus][ital x]]Fe[sub [ital x]])[sub 3]O[sub 7[minus][delta]] polycrystals for 0[le][ital x][lt]0.05 have been measured as a function of temperature and magnetic-field strength. Two different types of be

By using a highly sensitive homemade AC magnetic susceptibility technique, the magnetic flux penetration has been measured in YBa_2Cu_3O_7 single crystals with giant screw dislocations (having the structure of the Archimedean spirals) exhibiting a=3
