MAGNETIC FIELD GENERATORS FOR MAGNETO-OPTIC AND ELLIPSOMETRIC MEASUREMENTS

Jaromír Pištora – Michal Lesňák

   This paper deals with description of designing, fabrication and analysis of a magnetic field generators. These generators have been fabricated for magneto-optic and ellipsometric measurements. The modelling of the electromagnets based on ANSYS finite element software is described, various field configurations are discussed. The interest is focused on the distribution of magnetic flux density in the air gap located between the pole extenders. The results of discussed theoretical approach have been verified with experiments and good accord has been found.

Keywords: magnetic field generators, magneto optic, ellipsometry
