Vg. Baryakhtar et Ep. Stefanovskii, SYMMETRY-DEPENDENT INCOMMENSURATE-MAGNETI C PHASES IN MAGNETODIELECTRICS, Fizika nizkih temperatur, 22(8), 1996, pp. 904-911
Modern phenomenological theory of modulated longperiodic structures in
magnetically ordered crystals is analysed. Main attention is paid to
incommensurate magnetic phases which exist due to the free energy inva
riants linear with respect to the first space derivatives of the spin
density moments. Equilibrium magnetic configurations of some specific
objects are analysed.
