Recently thermally activated sine-Gordon solitons have been observed in the one dimensional magnetic systems TMMC 1,2 and CsNiF3 3-5 (actually, in CsNiF3 this is a point of discussion6-9). In this article we want to discuss the possibility to create nonthermal solitons in a one dimensional sine-Gordon system by a time dependent magnetic field. These nonthermal solitons will appear in addition to the thermally excited ones. This would open e.g. the possibility to study a nonequilibrium system and questions like soliton-soliton interaction (if the density is made high enough) and soliton diffusion (because they are created locally).
