  Patterns of ferroic domains and domain walls are being intensively studied to
implement new logic schemes. Any technological application of such objects
depends on a detailed understanding of them. This study analyzes patterns of
ferromagnetic stripes on equiatomic FePt thin films at low temperatures. Since
FePt is known to develop a transition from in-plane homogeneous magnetization
to stripes upon varying its thickness, multiple samples are studied to consider
the critical value within the analyzed range. Stripes' width demonstrates the
well-known Murayama's law while a non-trivial dependence on temperature is also
reported. Moreover, the room-temperature uniform distribution of the pattern
evolves into a distorted one upon temperature cycling. Finally, dissimilar
striped patterns are obtained upon reducing and increasing temperature
indicating the states are dependent on the history of applied stimuli rather
than the parametric conditions.
