Abstract In this paper, the various conditions under which the K‐dV solitons and double layers may be formed in a plasma that includes two electron‐temperatures are examined by deriving a “Further modified K‐dV” (FmK‐dV) equation in three dimensional space in which there is assumed to be an ambient magnetic field. Structural forms of the various ion‐acoustic waves are discussed by obtaining both soliton‐specific and double layer‐specific solitons of the FmK‐dV equation. Particular results are deduced as special cases of the more general cases.
