Correction of Measured Magnetization Curves Using Finite Element Method

Magnetic measurement accuracy for open samples is analyzed using numerical simulations. The finite element method is used for the complete numerical correction of experimental data which are measured with a vibrating sample magnetometer. The magnetization curves are recalculated taking into account...

Description
Summary:Magnetic measurement accuracy for open samples is analyzed using numerical simulations. The finite element method is used for the complete numerical correction of experimental data which are measured with a vibrating sample magnetometer. The magnetization curves are recalculated taking into account the demagnetizing field, the shape of the open magnetic circuit, and the field probe position.
