Induction of an incommensurate state by a periodically varying temperature field
Zhigadlo N. D. , Zaretskii V. V.
Observations reveal that a phase transition to an incommensurate phase can occur not only as the temperature (or the pressure or a field) is varied but also during the application of a periodically varying temperature field. It has been found that a periodically varying temperature field exhibits the properties of an external inducing agent which gives rise to an incommensurate structure. The relationship between the periodic temperature field and the incommensurate effects is discussed.
