  • Normally, any ferromagnetic or ferrimagnetic material undergoes a transition to a paramagnetic state above its Curie temperature. Superparamagnetism is different from this standard transition since it occurs below the Curie temperature of the material. Superparamagnetism occurs in nanoparticles which are single domain. This is possible when their diameter is below 3–50 nm, depending on the materials.

  • The idea of writing a book on neutron scattering from magnetic materials occurred to me about four years ago. I was then acting as a subeditor of the topic Neutron Scattering for the encyclopedic book “Scattering: Scattering and Inverse Scattering in Pure and Applied Science” which was to be published by Academic Press, London [1]. There I had to cover the field of neutron scattering in a very limited space and that was a very difficult and frustrating task indeed. I

  • The term magnetic bearing refers to devices that provide stable suspension of a rotor. Because of the contact-less motion of the rotor, magnetic bearings offer many advantages for various applications. Commercial applications include compressors, centrifuges, high-speed turbines, energy-storage flywheels, high-precision machine tools, etc. Magnetic bearings are a typical mechatronic product. Thus, a great deal of knowledge is necessary for its design, construction and operation.

  • Since its first implementation by Lauterbur [1], Magnetic Resonance Imaging (MRI) has become an important noninvasive imaging modality. MRI has found a number of applications in the fields of biology, engineering, and material science. Because it provides unique contrast between soft tissues (which is generally superior to that of CT) and high spatial resolution, MRI has revolutionized diagnostic imaging in medical science. An important advantage of diagnostic MRI as compared to CT is that the former does not use ionizing radiation....

  • Electromagnetism is fundamental to the whole of electrical and electronic engineering. It provides the basis for understanding the uses of electricity and for the design of the whole spectrum of devices from the largest turbo-alternators to the smallest microcircuits. This subject is a vital part of the education of electronic engineers. Without it they are limited to understanding electronic circuits in terms of the idealizations of circuit theory.

  • This is a companion volume to Electromagnetism for Electronic Engineers(3 rd edn.) (Ventus, 2009). It contains the worked examples, together with worked solutions to the end of chapter examples, which featured in the previous edition of the book. I have discovered and corrected a number of mistakes in the previous edition. I hope that students will find these 88 worked examples helpful in illustrating how the fundamental laws of electromagnetism can be applied to a range of problems.

  • In the last two decades, many books have been published on ion implantation and ion-beam processing. Why this one now? After all, the advantages of using an energetic ion beam to modify surfaces with a view to enhancing their tribological, electrochemical, optical and magnetic properties have been known for some time. The aim of this volume is to review the basics of previous work on ion-beam modification of materials and to include enough new material on novel applications to bring newcomers “up to speed” in this exciting area....

  • The purpose of these notes is be used to introduce Electrical Engineering students to Electrical Machines, Power Electronics and Electrical Drives. They are primarily to serve our students at MSU: they come to the course on Energy Conversion and Power Electronics with a solid background in Electric Circuits and Electromagnetics, and many want to acquire a basic working knowledge of the material, but plan a career in a different area (venturing as far as computer or mechanical engineering).

  • This book evolved from the first term of a two-term course on the physics of charged particle acceleration that I taught at the University of New Mexico and at Los Alamos National Laboratory. The first term covered conventional accelerators in the single particle limit. The second term covered collective effects in charged particle beams, including high current transport and instabilities. The material was selected to make the course accessible to graduate students in physics and electrical engineering with no previous background in accelerator theory.

  • Here DNA has been used as templating and self-assembling reagent to grow the chain like nanostructure. We have designed the composite in such a fashion that we obtained optical and magnetic properties together in a single biological material. Optical properties characterized by UV–visible absorption, Circular Dichroism (CD) and their analysis show no denaturization of DNA. Transmission electron micrographs (TEM) indicate formation of chain like structure of the nanoparticles. Particles were functionalized with folic acid for labeling and treatment of cancer cell.

  • Physical properties of metals, ceramics, and polymers, such as ductility, thermal expansion, heat capacity, elastic modulus, electrical conductivity, and dielectric and magnetic properties, are a direct result of the structure and bonding of the atoms and ions in the material. An understanding of the origin of the differences in these properties is of great engineering importance.

  • Material Selection. The material systems currently in commercial use include ferrous alloys (low-alloy steel, stainless steels, soft magnetic alloys), nonferrous alloys (brass, bronze), tungsten carbide, pure nickel, electronic alloys (Invar, Kovar), and tungsten-copper composites. The physical and mechanical properties of several MIM engineering alloys (low-alloy steel and stainless steels) have been standardized by MPIF (Ref 10).
