Abstract
In this publication, experimental curves from torque magnetometry will be compared with curves which are generated by numerical simulation. The experimental results refer to steady and to relaxation torque measurements of a film of the HTSC TlBaCaCuP. For simulation, a differential equation was solved. This equation is derived from a simple dynamic model which contains implicity the flux creep theory with logarithmic barrier and describes steady curves as well as relaxation curves. This method overcomes some problems which occur if experimental curves are fitted to analytical solutions. It is a promising attempt to extract material parameters from measurements of ring shaped samples. With out simulated curves we try to reproduce the shape of the measured curves as a first step. A detailed quantitative analysis is not yet the aim of this work.
