Giant magnetically induced twin variant reorientation, comparable in intensity with bulk single crystals, is obtained epitaxial magnetic shape-memory thin films. It found to be tunable and spatial response by the fine control of microstructural patterns at nanoscopic microscopic scales. A thorough experimental study (including electron holography) allows a multiscale comprehension phenomenon.
