From Bulk to Nano (eBook, PDF)

The Many Sides of Magnetism

• Format: PDF

Produktbeschreibung

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.

Autorenporträt

Dr. Stefanita is a physicist/materials scientist who received her Ph. D. degree in Physics (Magnetic Nondestructive Testing and Materials Characterization) from Queen's University, Kingston, Ontario, Canada in 1999. Her Ph.D. thesis is entitled "Surface Magnetic Barkhausen Noise Response To Plastic Yield of Steel". Previously, she received her Diploma of Engineer in Physics (Technological Physics) from the University of Bucharest, Romania in 1989 with the thesis entitled "Apparatus for Measuring Solar Radiation Using a Thin Film Transducer". Dr. Stefanita also has a 1984 Baccalaureate in Mathematics and Physics from the German School of Bucharest in Romania.

Dr. Stefanita has over 15 years collective experience in academia and industry with international exposure on 3 continents, and 5 countries. Her most recent research experience is in nanotechnology, in self-assembled metallic and semiconductor nanowires or nanodots, spintronics, magnetotransport, Hall effect, and infrared absorption and transmission, acquired during her work at Virginia Commonwealth University in Richmond, Virginia, USA.

Her previous work in magnetism in the 1990s at Queen's University involves magnetic behavior of plastically deformed steel, microyielding phenomena, cold rolling effects on magnetic properties; magnetic nondestructive testing techniques for detecting defects in steel components. She has also developed a prototype for a medical diagnostics apparatus based on a thin film interference filter, at the University of Alberta in Edmonton, Alberta, Canada.

Dr. Stefanita's previous work as a materials scientist in South Africa, and in Germany and Romania is in the areas of failure analysis, scanning electron microscopy, energy dispersive X- ray analysis, atomic emission spectroscopy and import of chemicals and raw materials.

Dr. Stefanita is a co-founder and Senior Partner with NanoDotTek based in the Bostonarea, Massachusetts, USA. This company is dedicated to promoting nanotechnology, and allied areas such as non-destructive testing (the "NDT" in NanoDotTek) for engineering systems. With respect to the latter Dr. Stefanita is presently engaged in developing a lossy dielectric with a prescribed fractional impedance. This is in furtherance of improving fractional order control systems and pulse shaping for wireless broadband communications. This work is in collaboration with engineers in California and Mexico.

Dr. Stefanita also has experience in teaching. Her lectures have covered solid state devices, electromagnetics, and mechanics of deformables.

Dr. Stefanita is a regular referee for nanotechnology papers, as well as a published author of journal papers, conference publications, and internal reports. The latter reports are in many cases in relation to contract-based research. Dr. Stefanita's most recent journal paper in spintronics appeared in Nature Nanotechnology earlier this year.

Finally, note that Dr. Stefanita is a licensed Professional Engineer in the Province of Alberta, Canada.
