Nk. Danshin et Yi. Nepochatykh, CONTRIBUTION OF LONGITUDINAL OSCILLATIONS OF MAGNETIZATION TO SPIN DYNAMICS OF SPONTANEOUS REORIENTATION, Low temperature physics, 24(4), 1998, pp. 267-272
Comparative analysis of the results of measurements of soft magnetic r
esonant modes in weak ferromagnets with different temperatures of spon
taneous reorientation is carried out. It is shown that the longitudina
l oscillations of magnetization make a contribution to the energy gap
even in zero magnetic field tin the case of spontaneous reorientation)
and increases with increasing temperature alone. (C) 1998 American In
