Ferromagnetism in relation to engineering magnetic materials. A review of progress

After a brief introductory account of the earlier development of the subject of ferromagnetism a review is given of theoretical and experimental work mainly within the past ten years. This includes an account of ferromagnetic domains and of the small-particle theory of high coercivity. A description of the ferrites and of ferrimagnetism is given, and this is followed by a discussion of recent observations and ideas on the magnetic phenomena occurring at frequencies up into the microwave region.
