We report on the continuous magnetization curves of a single crystal of vanadium having a resistivity ratio of 25. Our method is based on the electronic integration of the difference signal induced across two identical coils, one of which contains the specimen, as the external magnetic field is cycled over the operating range. The magnetization curves are analyzed to obtain the values of the Ginzburg-Landau parameters κ1 and κ2 as functions of temperature. The lower and upper critical fields as well as the thermodynamic critical field are also given as functions of temperature. The experimental data are compared with the theoretical calculations of Eilenberger and others.
