Electrophysical properties of nanoporous cerium dioxide–water system
Get PDFThe impedance of nanoporous cerium dioxide with adsorbed water is investigated in the frequency range 103–104 Hz at temperatures near the water–ice phase transition. Here we show that the manifestation of impedance peculiarities at phase transition is caused by the dielectric constant of the matrix

Modification of superconducting and resistive properties of HoBa2Cu3O7−δ single crystals under application-removal of high hydrostatic pressure
No full text The influence of a high hydrostatic pressure on the basal-plane electrical resistance along the twin boundaries in underdoped HoBa2Cu3O[Formula: see text] single crystals is investigated. An enhancement of the phase segregation caused by the high-pressure-induced redistribution of the labile oxygen has been revealed. The temperature dependences of the electrical resistance above [Formula: see text] can be approximated well within the framework of the model of [Formula: see text] electron–phonon scattering. </jats:p
