Magnetism And Metallurgy Of Soft Magnetic Materials

Magnetism and Metallurgy of Soft Magnetic Materials consistently and coherently presents the principles underlying the intrinsic and applied properties of soft magnets. This book is divided into two parts, focusing on magnetism and metallurgy.
The first part of this book provides the various kinds of magnetism and the fundamental quantities of magnetism, such as magnetic poles, magnetic dipole, magnetic moment, magnetic field and magnetic induction. The second and third chapters focus on the theories of ferromagnetism and ferrimagnetism, as well as their domain structure and magnetization processes. The next chapter deals with the different magnetic properties, such as the intrinsic properties and the two structure-sensitive properties, the static properties and the dynamic properties.
The second half of this book deals with the metallurgy and application of soft magnetic materials, such as the pure iron and steels, iron-silicon alloys, nickel-iron alloys, iron-cobalt alloys, ferrites, and thin films. Finally, this book offers special topics on radiation effects and magnetic bubbles and devices.
