The relativistic compressive solitons of fast ion-acoustic mode are established in this magnetized plasma for the introduction of relativistic beam when Q{sup '}(=m{sub b}/m{sub i})>1 or <1 subject to v{sub s{xi}0}-v{sub b{xi}0}=U{sub d} sin {theta} (v{sub s{xi}0}=ion initial streaming, v{sub b{xi}0}=beam initial streaming, and U{sub d} is the beam drift perpendicular to the direction of magnetic field). The lighter concentration of beam ions (Q{sup '}<1) in the plasma admits slower variation in amplitudes after some critical N{sub b} (=beam density) for all {sigma}{sub {nu}}(cos {theta}). Further, it is shown that under smaller relativistic effect (v{sub b{xi}0}/c=0.10 and v{sub s{xi}0}/c=0.10) for small concentration of beam ions (Q{sup '}<1) in the plasma, the growth of soliton amplitude becomes smaller with the increase of N{sub b}. But to the contrary, for heavier concentration of beam ions Q{sup '}(>1), the amplitudes of solitons decay considerably with Q{sup '} growing sharply to a maximum in the vicinity of Q{sup '}{approx_equal}1.
