Abstrakt: The magnetic structure of the iron monoarsenide FeAs is studied using first-principlescalculations. We consider the collinear and non-collinear (spin-spiral wave) magnetic orderingand magnetic anisotropy. It is analitically shown that a magnetic triaxial anisotropy resultsin a sum of two spin-spiral waves with opposite directions of wave vectors and different spinamplitudes, so that the magnetic moments in two perpendicular directions do not equal eachother.
