GENERAL INFO

Instructor:   Nicola Spaldin, Room 2007 MRL x7920, nicola@mrl.ucsb.edu
Office Hours:  Thursday 10.30 am - noon. Room 2007 MRL

COURSE SUMMARY

1st half:
review of elementary magnetostatics
atomic origins of magnetism
ferro-, ferri-, para-, dia- and antiferro-magnetism
modern theories of magnetism

2nd half:
magnetic phenomena; survey of magnetic materials in technological applications

Assessment:
Grading will be determined by homework problems (20% of the grade), two in-class "mini mid-terms" (40%), plus an abstract (10%) and presentation (30%) on a topic of your choice in magnetic materials.
 

REQUIRED TEXT

N. A. Spaldin, Magnetic materials; Fundamentals and device applications (Cambridge University Press, 2003). 

For obvious reasons, photocopying the text book will be considered grounds for failing the class ;-) 


RECOMMENDED TEXTS

S. Blundell, Magnetism in condensed matter (Oxford University Press, 2003)
D. Jiles, Introduction to magnetism and magnetic materials (Chapman & Hall, 1996)
B. D. Cullity, Introduction to magnetic materials (Addison-Wesley, Reading, Mass., 1972)
 

IDEAS FOR YOUR PRESENTATION TOPIC:


You will be allowed 15 minutes to make your presentation.

Here is the grading scheme for your presentation (out of a possible total of 30):

Organization [8]: 2 points for a good outline/overview, 2 points for a good summary/conclusion and 4 points for the organization in between. The latter includes timing and pitching the discussion at the correct level, as well as knowing what you're going to say when

Clarity [6]: of speech (3), and of the written presentation material/overheads (3)

Level of interest [8]: to the other students (3) and to me (3), and Relevance to the course/society/something (i.e. "why are you doing this?") (2)

Knowledge [8]: Your knowledge about the topic during the presentation (4), and in response to questions (4)

HOMEWORK ASSIGNMENTS

Homework 1  In case you didn't already find them, here are the solutions

Homework 2: Problems 3.2, 4.1 and 5.2 from the text book. Also compare your answers in 4.1 and 5.2. You should complete these problems before the first mid-term, and check the solutions at the back of the book. You don't need to turn them in for grading.

Homework 3

Homework 4: Problems 9.1 and 9.2 from the text book. You should complete these problems before the second mid-term, and check the solutions at the back of the book. You don't need to turn them in for grading.


Notice that, whenever the homework is a problem out of the text book, you'll find the solutions at the back of the book! You should have a go at the problem yourself, and if you get stuck, take a look at the solution, or come and ask me. Then you should attempt the final write-up without peeping at the solutions again. The purpose of the homework assignments is to give you some new things to think about which we'll then discuss in class, and to give you some practice in solving problems - obviously the points come almost for free....
