Students will:

Understand the principles of calorimetric methods, control different types of calorimeters, evaluate data and their uncertainty.

Understand principles of solid magnetism and magnetometry, learn methods of evaluation and interpretation of magnetic properties.

Understand the principles of measuring the electrical transport properties of materials. Measurement of resistivity-conductivity (direct method, 4 point method, van der Pauw method) further measurement of the charge and mobility of the charge carriers in different types of materials (insulators, semiconductors, metals, superconductors).
