Abstract

In this study, static and dynamic of vortex in Y₁Ba₂Cu₃O_7-δ system have been investigated depending on the magnetic field and temperature. The Y₁Ba₂Cu₃O_7-δ samples were prepared using conventional solid-state reaction technique at two different sintering temperatures (900, 920°C). Magnetic fields dependence of the magnetic moments in the Y₁Ba₂Cu₃O_7-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 Y₁Ba₂Cu₃O_7-δ single crystal were investigated 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.
