From Bulk to Nano: The Many Sides of Magnetism (Springer Series in Materials Science Book 117)

the Field Of Magnetism Is Rapidly Advancing In This New Millennium, Revealing An Ever-wider Diversity Of Magnetic Phenomena On More Than One Scale. With The Emergence Of Countless Applications Particularly On A Nanoscale, And Their Unpredictable Implications Mostly On A Macroscale, It May Seem That Different Aspects Of Magnetism Are Unrelated. Quite Often, The Overwhelming Amount Of Topics Discussed In The Professional Literature Views Only Parts Of A Field, Ignoring A Broader Context. Therefore, The Present Book Aims At Addressing The Relationship Between Apparently Unconnected Topics In Magnetism. Less Obvious Relationships Are Revealed Among Individual Fields On Various Scales, Making Them Better Understandable. The inspiration for this book can be traced back many years to two major works that in?uenced the author’s outlook on applied physics: FerromagnetismusbyR. Becker,W. D ̈ oring (Springer, Berlin 1939), and Ferromagnetism by R. M. Bozorth (IEEE Press, New York 1951). The former work is a collection of lectures held in the 1930s for ‘technicians’ attending a technical college. The German language in which the work was originally written was extremely convenient for the author of this present book, as it was for a long time the only comfortable technical language in an English speaking environment. Later on, upon encountering the work by Bozorth, it was a relief to see the clarity and eloquence of the subjects presented in English, despite the impressive thickness of the book. Bozorth’s work still constitutes a practical review for anyone in a multidisciplinary industry who comes across the various manifestations of magnetism. The popularity of both works is so enduring that they are regarded as highly academic, and yet extremely readable, a reference in their own right, still attracting many readers these days in industry and academia. The ?eld of magnetism progressed immensely in the twentieth century, and shows no signs of slowing down in the present one. It has become so vast that it is quite often viewed only in its parts, rather than as a whole. In today’smyriadofapplications,especiallyonananoscale,andtheirchangeable implications mostly on a macroscale, it often seems that di?erent aspects of reported work on magnetism are scattered and unrelated. This book deals with the latest achievements in the field of ferroelectric domain engineering and characterization at micron- and nano-scale dimensions and periods. The book collects the results obtained in the last years by world scientific leaders in the field, thus providing a valid and unique overview of the state-of-the-art and also a view to future applications of those engineered materials in the field of photonics Front Matter....Pages I-XX Introduction....Pages 1-17 Barkhausen Noise as a Magnetic Nondestructive Testing Technique....Pages 19-40 Combined Phenomena in Novel Materials....Pages 41-70 Magnetoresistance and Spin Valves....Pages 71-98 Some Basic Spintronics Concepts....Pages 99-127 Trends in Magnetic Recording Media....Pages 129-160 Concluding Remarks....Pages 161-161 Back Matter....Pages 163-174 This text addresses the relationship between apparently unconnected topics in magnetism.
