The interpretation of the physics of magnets with reduced dimensionality often requires information on the
spin wave excitations at arbitrary wavelengths which is generally hard to obtain experimentally. Two powerful
methods for the ab initio calculation of adiabatic spin-wave spectra are introduced, a frozen-magnon-torque
method for systems with large exchange fields and a transverse-susceptibility method which may be used also
for materials with smaller exchange fields. The efficiency of both methods results from the fact that the number
of calculations required to obtain the spin-wave spectrum scales linearly with the number of basis atoms in the
unit cell. Results are given for Fe, Co, Ni, permalloy Ni3Fe, and CoFe, materials which are often used for
