Magneto-optical magnetometry of ferromagnetic thin films with flexible substrate
 Střihavková, Julie ; Schmoranzerová, Eva (advisor) ; Hamrle, Jaroslav (referee)
This work is focused on measurements of magnetooptical effects in thin magnetic multilayers prepared on a flexible substrate. A main goal of this thesis was to deter- mine ideal conditions of the experiment, suitable for studying this type of sample with a magnetooptical method. In the measurements were determined artifacts caused both by the experimental setup and by effect of the flexible substrate on the polarization state of transmitted light. An approximate value of the magnetic anisotropy of the ferromagnetic layer (Co), connected with apresence of strain in the system, was determined using a ROT-MOKE method. The calculated values of the anisotropy field were burdened with a significant measurement error. We can thus conclude that the magnetooptical method can be used for the study of the changes of magnetic properties (i.e. thermally induced strain). However, regarding determination of the exact values of the magnetic anisotropy, the method has its limitations. 1
