We report on measurements of the temperature dependence of resistivity, , for single crystal samples of ZrB, ZrB and polycrystalline samples of MgB. It is…
Raman spectra of MgB2 at high pressure and topological electronic transition
K. P. Meletov, J. Arvanitidis, M. P. Kulakov +2
Raman spectra of the MgB2 ceramic samples were measured as a function of pressure up to 32 GPa at room temperature. The spectrum at normal conditions contains a very broad peak at…
Synthesis of MgB2 from elements
N. N. Kolesnikov, M. P. Kulakov
Superconducting at 40 K MgB2 -samples were obtained by direct reaction from elements in molybdenum crucibles under argon pressure. Pressure allows to provide annealing at temperatu…
Characteristic features of the temperature dependence of the surface impedance in polycrystalline MgB samples

Effect of pressure on the superconducting Tc of MgB2
V. G. Tissen, M. V. Nefedova, N. N. Kolesnikov +1
Measurements of the superconducting transition temperature Tc have been performed by the inductive method on MgB2 at pressures up to 28 GPa. Tc decreases with applied pressure, exh…
Electron Transport in Diborides: Observation of Superconductivity in ZrB2
Vitaly A. Gasparov, N. S. Sidorov, I. I. Zver'kova +1
We report on syntheses and electron transport properties of polycrystalline samples of diborides (AB2) with different transition metals atoms (A=Zr,Nb,Ta). The temperature dependen…
