    • [Formula Omitted] is actually the anhysteretic value of the magnetization, which is not known in the present case. However, a reasonable approximation is to assume that [Formula Omitted] when the field is positive (negative).

    • We will assume for [Formula Omitted] the value of the bulk material at the same temperature.

    • One does not need to consider Néel walls; indeed, as is easily verified, in film with perpendicular easy axis, the latter are more energetic than Bloch walls.

    • The model of plane rigid walls moving in a one‐dimensional potential has often been used without any justification and led to erroneous results, as pointed out by Néel in Ref. 15; it is generally not recognized that it is only when the wall energy fluctuations are smooth enough [Formula Omitted] that it is possible to linearize the problem and to reduce it to a one‐dimensional one. Néel’s variational theory allows to precise the conditions of this simplification, and to determine the parameters of the effective potential.
