Description
From the Preface Magnetic materials development can been associated to some periods of humankind historical progress: from the discovery of loadstone (reported by the Greeks between 300-400 B.C.) which allowed the fabrication of compasses and concomitantly, the development of long route navigation, to magnetic recording media, which has afforded the appearance of increasingly powerful computers and massive storing devices, thus influencing to a great extend our modern lifestyle.
Since the discovery of magnetite, many types of magnetic materials have been studied for a very wide range of applications. For instance, soft magnetic materials, characterized by high magnetic permeability values, are useful for electric engineering and power electronics concerning production, transportation and the use of electrical energy (dynamos, alternators, transformers or motors) as well as for low power applications (sensors, small transformers, telecommunications devices). On the other side, hard magnetic alloys, with high remanence magnetisation and energy density values, are also used for a very wide range of applications: uniform and non-uniform magnetic field sources, magnetic separation, levitation systems, actuators, sensors, motors (dc, synchronous, stepping) and even for biomedical devices (cardiac valves, magnetic catheters, dental care). In this book, we devote four chapters for these kinds of materials, describing both fundamental and practical up-to-date aspects of amorphous soft magnetic wires (Chapters 1 and 2) and of hard magnetic alloys (Chapters 3 and 4). In addition, Chapter 5 and 6 focuses on basic phenomena of current interest for two types of magnetic ceramic materials: manganites and magnetite (a surprisingly magnetic material, which is still under discussion after 2500 years!). Finally, a novel magnetosensitive power absorption technique for phase transitions is presented in Chapter 7. Although not being an exhaustive treatise on magnetic materials, this book intends to give a general overview on recent research topics on amorphous wires, hard magnetic alloys and magnetic ceramics.
