In this study, static and dynamic of vortex have been investigated in Y1Ba2Cu3O7- δ system depending on the magnetic field and temperature. The Y1Ba2Cu3O7- δ system was fabricated under different heat treatments between 900-920°C for 24 h. using conventional solid-state reaction technique. Magnetic fields dependence of the magnetic moments in the Y1Ba2Cu3O7- δ single crystal M-H measurements were carried out for different temperatures (10, 20 and 30 K).Temperature dependence of the magnetic moments in the Y1Ba2Cu3O7- δ single crystal by applying constant 500 Oe magnetic field. Vortex lattice thermal fluctuations, magnetic fields and random pinning favour a liquid or a disordered glassy vortex state. The non-equilibrium states contain several types of plastic and elastic motion.

The Y1Ba2Cu3O7- δ system was fabricated under different heat treatments between 900-920°C for 24 h. using conventional solid-state reaction technique. Magnetic fields dependence of the magnetic moments in the Y1Ba2Cu3O7- δ single crystal M-H measurements were carried out for different temperatures (10, 20 and 30 K).Temperature dependence of the magnetic moments in the Y1Ba2Cu3O7- δ single crystal by applying constant 500 Oe magnetic field. Vortex lattice thermal fluctuations, magnetic fields and random pinning favour a liquid or a disordered glassy vortex state. The non-equilibrium states contain several types of plastic and elastic motion.
