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 term paper (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 ;-)

HOMEWORK ASSIGNMENTS
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....
