On amplitude oscillation of vibrations of strongly anisotropic high-temperature superconductors of BiPbSrCaCuO system

Abstract

Effect of oscillations of the vibration amplitude of cylindrical sample suspended by a thin elastic thread and vibrating in a transverse magnetic field and containing 2D quasi-two-dimensional vortices (pancakes), was observed in the strongly anisotropic high-T c superconductor of Bi 1.7 P b 0.3 Sr 2 Ca 2 Cu 3 O y system.

Investigation of stimulated dynamics in strongly anisotropic high-temperature superconductors system Bi–Pb–Sr–Ca–Cu–O

“…Such phase transition takes place in high-temperature superconductor system Bi 1.7 Pb 0.3 Sr 2 Ca 2 Cu 3 O 10-δ [12,13]. During this transition a sharp dissipation energy decrease of moving Abrikosov vortices (almost two orders of value) takes place what in its turn could be related with an essential decrease of pinning force.…”

“…Due to the layered crystal structure and anisotropy, which are characteristic of high-temperature superconductors, it is created conditions for the appearance on B-T diagram. ( B is magnetic induction, T-is temperature) different phases [4][5][6][7][8][9][10][11][12][13][14][15].…”

The investigation of EPR paramagnetic probe line width and shape temperature dependence in high-temperature superconductors of Bi–Pb–Sr–Ca–Cu–O system

“…Due to the layered crystal structure and anisotropy of HTSC, these conditions satisfy many prerequisites for a phase transition [6][7][8][9][10][11][12][13][14][15][16][17]. For example, in the Bi-Pb-Sr-Ca-Cu-O(2223) system the three-dimensional 3D Abrikosov vortices experience a phase transition in the quasi-two-dimensional 2D vortices, * Corresponding author.…”

Investigation of relaxation phenomena in high-temperature superconductors HoBa2Cu3O7−δ at the action of pulsed magnetic fields

“…It creates prerequisites for phase transitions. Due to the layered crystal structure and anisotropy, which is a characteristic for high-temperature superconductors, they reveal conditions for the appearance of different phases in the B−T diagram (B is magnetic induction, T is temperature) [2][3][4][5][6][7][8][9][10][11][12][13]. For example, the Abrikosov vortex lattice begins to melt near the critical T c temperature which is followed by an essential change of vortex continuum flow dynamics along with a sharp change of character (dynamics) of the relaxation phenomena.…”
