Opportunities in Magnetic Materials

Science, 1985
Recent discoveries of new magnetic materials may greatly improve the performance of devices containing such materials and may lead to entirely new applications. For example, boron-based temary compounds for permanent magnets make new compact motor designs practical; amorphous transformer materials show greatly reduced losses at high frequencies; and ...

Permanent Magnet Materials

Transactions of the American Institute of Electrical Engineers, 1936
Permanent magnet materials recently have been developed with characteristics radically different from those of previous materials, the carbon, cobalt, and chromium steels. In this paper, the essential properties of these new materials are discussed and are compared with the corresponding properties of the older materials.

Magnetic properties of materials

1993
The magnetic properties of materials only receive a satisfactory microscopic explanation by reference to the quantum structure of the constituent atoms and molecules. Quantum states of electrons are always dynamic in nature and they can involve surprisingly large internal electric currents.

Magnetic Materials and Permanent Magnets

2000
The historical and physical background of ferromagnetic materials technology, together with development of applied electromagnetic field theory and its computation techniques are reviewed. A comparative study of magnetic material properties, such as B/H curves, hysteresis loops, and power losses has also been covered.

Magnetism and magnetic properties of materials

1993
Some magnetic behaviour has been known and used for many centuries. The earliest experiences of magnetic properties concerned the behaviour of magnetite, which is the only material which occurs naturally and shows obvious magnetic behaviour. It was this mineral which provided lodestone; it was known more than 2000 years ago to both the Greeks and ...

Magnetic Materials and Magnetization Process

2018
This chapter presents the description of materials from the point of view of their magnetic properties. Physical principles of mechanisms of magnetization of ferromagnetic magnetic materials, covering domain wall bending, domain wall movements and domains rotations are elaborated.
