Long-lived nuclear spin order : theory and applications /
A long-lived form of spin order, namely singlet order, can be prepared from nuclear spin magnetisation and this first book on the subject gives a thorough description of the various aspects that interfere in the development of the topic and details the interdisciplinary applications.
