Exercise 2.1 - Magnetic Anisotropy
The content of the
Magnetic materials have a great impact on our daily life. A wide range of magnetic materials are 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 the magnetic anisotropy, where anisotropy means 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.
Link to the remote exercise registration is here. Reservation is open until 31.3.2021. Maximum number of students accepted to this exercise is 15. You need to request for the model data from the assistant by the end of March (at that time the model data will be automatically sent to those participants who had not yet asked for it).
The first version of the report must be returned to the exercise assistant electronically no later than three weeks after the model data has been received. The writing time for the second revised version, in turn, is two weeks, calculated from the assistant's invitation to the feedback session.
The reports will be returned to the assistant by email. The reports should be written only in English.
Material and measurement
Before requesting the model data, read carefully the instruction, where more information on the experiment and report can be found. In addition, watch the demonstration videos carefully and read the sections "Kurssin suorittaminen" and "Selkkariohjeita" in MyCourses. Then request the model data from the assistant.
