Fabrication and characterization of ferromagnetic vortices for spintronics
The proposed project involves creating thin ferromagnetic films which behave with reduced dimensionality to create concentrated localized magnetic fields. The initial part of the project is to create thin ferromagnetic disks with a thickness of approximately 50nm and a diameter of approximately 1 to 10 μm. This process involves various techniques such as photolithography and wet etching to develop the proposed films. The second part of the project involves measuring the magnetization of the films using techniques such as the Magneto Optical Kerr Effect and Magnetic Force Microscopy. It is expected that the magnetization of the films will create a vortex structure that results in a localized magnetic field normal to the plane of the sample at its center. The localized magnetic fields created by the films are intended to be used in further research on the spintronics of electrons.
