Temperature dependence of magnetization for FeGa/PVDF film in cooling and warming processes between 280 and 320 K under (a) different magnetic fields ranging from 0 to −25 Oe, (b) −20 Oe and (c) 20 Oe. The orientations of FeGa domains during thermal cycling under 0, −20 and 20 Oe are schematically shown in the insets of a, b and c, respectively. (d) Magnetization of FeGa/PVDF film reversed by thermal cycling under an alternatively positive and negative magnetic field. Top: thermal cycles between 280 and 320 K. Middle: an alternatively positive and negative magnetic field used for the measurements. Bottom: measurements of magnetization under the sequence of thermal cycles and magnetic field.
