This lab exercise is not suitable for people with a pacemaker or any other devices which are sensitive to magnetic fields!

The content of the work

Magnetic materials have a great impact on our daily life. A wide range of magnetic materials is used in different forms for the benefit of society. Magnetic thin films for example are used in computer hard disk drives, magnetic sensors and microwave devices. One of the main aspects of magnetism is the control of magnetic anisotropy, where anisotropy means a difference in energy depending on the direction of magnetization.

The purpose of this work is to understand the fundamentals of magnetic anisotropy and to investigate the anisotropy of magnetic thin films by using magneto-optical Kerr microscope.
