Query: Condon domains - these non-magnetic diamagnetic domains   The paper, not pretending for a complete and detailed review, is intended
mainly for a wide community of physicists, not only specialists in this
particular subject. The author gives a physical picture of the periodic
emergence of instabilities and well-known diamagnetic domains (Condon domains)
in metals resulting from the strong de Haas-van Alphen effect. The most
significant experiments on observation and study of the domain state in metals
are described. In particular, the recent achievements in this area using muon
spin rotation, as well as the amazing phenomenon of "supersoftness" observed in
the magnetostriction experiments, are presented. Novel, not previously
discussed features of the phenomenon related to the metal compressibility are
enlightened.
