Learning Outcomes

On successful completion of this module students should be able to:

Explain and apply the concept of reciprocal space.

Describe experimental techniques such as phonon spectroscopy and diffraction.

Distinguish material classes such as crystals, polymers, liquids, and glasses according to their structure.

Analyse crystallographic data and interpret them in terms of structural symmetry.

Describe the interaction of solids with magnetic fields and distinguish dia-, para- and ferromagnetism.

Analyse the magnetic and electric properties of solids in terms of collective magnetic and electric phenomena.

Interpret the thermal properties of crystal lattices using the Einstein and Debye models and predict their dispersion relations and heat capacities.


This module will equip students with the concepts needed to interpret and predict the properties of solids in terms of their structure. They will be introduced to a number of experimental techniques to determine structure and will be able to interpret structural data in terms of crystal symmetry. Different states of magnetism in solids are discussed and collective magnetic phenomena explained.

Brief description

This course will provide the physics behind the structural and magnetic properties of materials. Starting from descriptions of crystal structures and symmetry, the thermal properties of lattices ae discussed, and the magnetic properties of materials will be discussed in detail. The module includes sections about relevant experimental techniques such as x-ray diffraction and phonon spectroscopy.
