APPLIED MAGNETISM AND SUPERCONDUCTIVITY - 2022/3
Module code: PHY3056
In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.
These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.
Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.
This module is designed to provide a broad overview of quantum magnetism and superconductivity and their applications in modern science and technology. Both superconductivity and magnetism are manifestations of electronic charge and spin, and constitute prime examples of phase transitions in metals. A range of phenomena that is resulting from these phase transitions is surveyed. A significant part of the module is devoted to technological applications in magnetometry and spintronics.

|Assessment type||Unit of assessment||Weighting|
|Coursework||COURSEWORK ASSIGNMENT 1 (SUPERCONDUCTIVITY)||15|
|Coursework||COURSEWORK ASSIGNMENT II (MAGNETISM)||15|
analytical ability by solution of unseen problems in both coursework and exam
subject knowledge by recall of both “textbook” theory and important research articles in the exam
ability to generalize text-book theory by open-ended research component in the coursework
Thus, the summative assessment for this module consists of:
a 2 hour exam with 2 sections: Section A - Superconductivity (10 mark questions, answer 2 out of 3 ) & Section B: Magnetism (10 mark questions, answer 2 out of 3), weighted at 70%
2 assignments on specials topics, which will take a total of 40 hours of effort, each weighted at 15% - total of 30%
Formative assessment and feedback
Students will receive verbal feedback on progress with problems in tutorials and model solutions to the tutorial questions.
- This module aims to: To provide an introduction to the important role that electronic interaction plays in solid-state physics leading to phase transitions in electronic systems. To provide an introduction to microscopic theory and phenomenology of both quantum magnetic phenomena and superconductivity. Introduction to applications of solid state physics to micro-electronics and metrology.

Overall student workload
Methods of Teaching / Learning
The learning and teaching strategy is designed to provide:
a comprehensive theoretical treatment for the subject knowledge
practice in problem solving for the cognitive skills
The learning and teaching methods include:
“chalk and talk” lectures backed up with guided study to stimulate uptake of subject knowledge (2 hour per week x 11)
tutorial demonstration of solutions to key problems after students have attempted them for formative feedback (1 hour per week x 11)
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
