Observations of Bitter patterns were carried out for two varieties of Ni&sngbnd;Fe alloy thin films electrodeposited without magnetic field onto mechanically polished copper substrates. These two sorts of films were composed of 80Ni‐20Fe ``Film 1'' and 82.5Ni‐17.5Fe ``Film 2'' and were Fe‐rich and Ni‐rich from the composition of 81.5Ni‐18.5Fe with minimum coercive force. The behavior of magnetic domains was examined during various magnetic processes and under externally applied stress. It was found that: (i), in ``Film 1,'' the easy axis is parallel to the scratches on the substrates and the domain walls fall into those scratches; and (ii), in ``Film 2,'' an averaged easy direction is induced perpendicular to the scratches in several films, whereas in the other films it was not well‐established. These results are well explained, being consistent with the hysteresis characteristics, by assuming that magnetostriction is positive in ``Film 1'' and negative in ``Film 2'' and that magnetoelastic and shape anisotropies both are induced, accompanying the scratches on the surface of the substrates.
