  Noncollinear magnetic interfaces introduced in superconductor
(SC)/ferromagnet/SC heterostructures allow for spin-flipping processes and are
able to generate equal-spin spin-triplet pairing correlations within the
ferromagnetic region. This leads to the occurrence of the so-called long-range
proximity effect. Particular examples of noncollinear magnetic interfaces
include Bloch and N\'{e}el domain walls. Here, we present results for
heterostructures containing Bloch and N\'{e}el domain walls based on
self-consistent solutions of the spin-dependent Bogoliubov$-$de Gennes
equations in the clean limit. In particular, we investigate the thickness
dependence of Bloch and N\'{e}el domain walls on induced spin-triplet pairing
correlations and compare with other experimental and theoretical results,
including conical magnetic layers as noncollinear magnetic interfaces. It is
shown that both, Bloch and N\'{e}el domain walls lead to the generation of
unequal-spin spin-triplet pairing correlations of similar strength as for
conical magnetic layers. However, for the particular heterostructure geometries
investigated, only Bloch domain walls lead to the generation of equal-spin
spin-triplet pairing correlations. They are stronger than those generated by an
equivalent thickness of conical magnetic layers. In order for N\'{e}el domain
walls to induce equal-spin spin-triplet pairing correlations, they have to be
oriented such that the noncollinearity appears within the plane parallel to the
interface region.
