The aim of the course Magnetism and magnetic material is to provide an introduction to the key concepts and phenomena in magnetism which is a very important, interesting and dynamic area of solid state physics. In the first part an overview of the magnetic properties of the conventional magnetic materials including their applications is given. The second part provides an overview of current research of new magnetic phenomena and materials giving students an incentive to be actively involved by doing diploma thesis in this area.
LEARNING OUTCOMES AT THE LEVEL OF THE PROGRAMME:
1. KNOWLEDGE AND UNDERSTANDING
1.1 formulate, discuss and explain the basic laws of physics including mechanics, electromagnetism and thermodynamics
1.2 demonstrate a thorough knowledge of advanced methods of theoretical physics including classical mechanics, classical electrodynamics, statistical physics and quantum physics
1.3 demonstrate a thorough knowledge of the most important physics theories (logical and mathematical structure, experimental support, described physical phenomena)
2. APPLYING KNOWLEDGE AND UNDERSTANDING
2.1 identify the essentials of a process/situation and set up a working model of the same or recognize and use the existing models
2.2 evaluate clearly the orders of magnitude in situations which are physically different, but show analogies, thus allowing the use of known solutions in new problems;
2.3 adapt available models to new experimental data
3. MAKING JUDGEMENTS
3.1 develop a personal sense of responsibility, given the free choice of elective/optional courses
4. COMMUNICATION SKILLS
4.1 work in an interdisciplinary team
5. LEARNING SKILLS
5.1 search for and use physical and other technical literature, as well as any other sources of information relevant to research work and technical project development (good knowledge of technical English is required)
5.2 remain informed of new developments and methods and provide professional advice on their possible range and applications
5.3 carry out research by undertaking a PhD
LEARNING OUTCOMES SPECIFIC FOR THE COURSE:
By successfully completing the course Magnetism and magnetic materials, student will be able:
* to explain qualitatively the origin of magnetism in materials;
* to describe qualitatively and quantitatively the magnetic properties of the conventional magnetic materials;
* to explain qualitatively magnetic phenomena on nanometer scale;
* to describe qualitatively the magnetic properties of the novel materials (magnetic semiconductors, multiferroics, ..);
* to give an overview of the magnetic materials applications in modern technologies e.g. IT and biotechnology;
* to start research by doing diploma thesis in this area.
