Year CATS Level Semester CATS Value
Session 2021-22 Level 6 FHEQ Second Semester 7.5

Aims

Students will develop an understanding of the phenomena and fundamental mechanisms of magnetism in condensed matter. They will be able to assess and compare the quantum mechanical interactions at play in different solids, and their impact on observable magnetic properties.


Learning Outcomes

(LO1) Atomic structure basis for magnetic moments.

(LO2) Definition of Magnetisation, magnetic susceptibility, diamagnetism, paramagnetism

(LO3) Magnetic moments of ions.

(LO4) Crystal fields and local environments

(LO5) Magnetic ordering, M vs T curve.

(LO6) Types of magnetic order: Ferromagnetism, antiferromagnetism, ferrimagnetism.

(LO7) Quantum origin of magnetism

Teaching and Learning Strategies

10 x 1 hour lectures (asynchronous, online)
Lectures cover core material for the course

5 x 1 hour group discussion sessions (synchronous, online)
Sessions covering worked examples of core material for the course

2 x 1 hour tutorials (synchronous, online)
Discussion of set problems

The module will be delivered remotely in 2021. Asynchronous learning materials (notes/videos/exercises etc) will be made available to students through the VLE. The module will have regular synchronous sessions in active learning mode.
We are planning no changes to module content compared to previous years, and expect students to spend a similar amount of time-on-task compared to previous years. These changes will mainly constitute a rebalancing of hours from scheduled directed learning hours to unscheduled directed learning hours as students will have some flexibility as to when they access asynchronous materials.
