摘要：

Giant ferro-vesicles made with a lipidic bilayer and filled up with a chemically synthesized magnetic fluid present undulations of the membrane in zero field. A magnetic field externally applied flattens the thermal undulations, induces a shape deformation of the vesicle and makes it lengthen along the field direction. We analyse the field-dependent elongation of the ferro-vesicle and compare it to the theoretical model.
