1-x CaxMnO3 films under the influence of temperature, topographic sample defects and external magnetic field. At low temperatures, typically about 140 degrees below Tc=245 K, domains were strongly coupled to each other, but could still be affected by thermal fluctuations. As we warmed the sample up, domains became highly mobile near Tc. Near Tc, sample scratches were able to capture nearby domains, whereas they did not affect domains when temperature is much lower than Tc. Above Tc all domains disappeared, with some of them disappearing earlier.
