Mechanical stress induced change in ferromagnetic Curie temperature in metal thin film magnets

It is very difficult to control properties of magnets once they have been prepared. If their properties can be controlled afterward, the variety of an application possibility will be increased. It is well known that the magnetization direction can be controlled by an application of mechanical stress. But experimental reports on the stress dependence of magnetic force or Curie temperature are not many. In this research, we prepared thin film magnets using accessible metal elements, and investigated the change in Curie temperature under the application of the mechanical stress.
