For example, the magnetic interaction of the electrons in the shell of iron atoms (below iron's characteristic Curie temperature of about 770[degrees]C) forces a spontaneous alignment in one direction of the spins of all the electrons, creating through this mutual enslavement process a phenomenon familiar to us as ferromagnetism
Two separate chapters are devoted to nanostructures of carbon and to ferromagnetism
Multiferroics: that is, materials which simultaneously exhibit both ferromagnetism
and ferroelectricity - and also often ferroelasticity - now attract considerable attention because of the interesting physics involved and their promise for important practical applications.
They cover magnetic oxides; dopants, defects, and ferromagnetism
in metal oxides; ferroelectrics; multiferroics; interfaces and magnetism; and devices and applications.
The situation has been summarized as follows, "Whereas technical dynamos consist of a number of well-separated electrically conducting parts, a cosmic dynamo operates, without any ferromagnetism
, in a nearly homogeneous medium" .
Among the invited papers are discussions of III-nitride and its application for optoelectronic devices, the ferromagnetism
and luminescence of diluted magnetic semiconductors GaGdN and AlGdN, the magnetic resonance study of non-equivalent centers created by 4f-ions in congruent and stoichiometric lithium niobate, ultrafast emitting oxidic Pr3+ scintillating materials for medical applications, and thulium-doped phosphors under vacuum ultraviolet excitation.
In common magnets, such as iron and nickel that consist of a repeating crystal structure, ferromagnetism
occurs when unpaired electrons within the material spontaneously align in the same direction.
