COURSE DESCRIPTION
This course covers the fundamentals of magnetism and magnetic materials in the first two thirds of the class. Topics include classical versus quantum mechanical pictures, diamagnetism, paramagnetism, crystal field environments, dipolar and exchange interactions, ferromagnetism, antiferromagnetism, magnetic domains, magnetic anisotropy and magnetostriction. Magnetic materials covered include transition metals, their alloys and oxides, rare earths and their oxides, organic and molecular magnets etc.. Throughout the course, experimental techniques in magnetic characterization will be discussed. The second part of the course will focus on particular magnetic materials and devices that are of technological interest (e.g., magnetoresistive and magneto-optical materials and devices). Additional topics include biomagnetism and spin glasses.

COURSE OBJECTIVES
The purpose of this course is to introduce students to the fundamental concepts in magnetism and to apply them to our understanding of magnetic materials and devices in the world around us. The coursework assumes knowledge of basic electromagnetism, familiarity with some quantum mechanics and a course either in electronic properties of materials (Mat Sci 111) or an introductory solid state physics course. Through the lectures and readings from the text as well as the literature, students will develop an understanding of basic concepts in magnetism and how to apply them to advanced materials and devices. Materials used in devices for information storage, power and medical applications will be addressed.
