Imaging Magnetic Domain Morphologies in Co/Pt Multilayer with 4Å of Cobalt

ORAL

Abstract

We have studied the magnetic domains that form perpendicular to the film of our multilayer Co/Pt thin film with 4Å of Cobalt. When an external magnetic field is applied, the domains create morphologies that vary based on the strength of the magnetic field. These morphologies vary from maze-like to bubble patterns. We used a Vibrating Sample Magnetometer (VSM) to apply the fields to our 4Å Co/Pt thin film. A Magnetic Force Microscope (MFM) was also used to obtain images of the magnetic domains of the sample in the absence of the field. We were able to find the field at which greatest number of domains was achieved by analyzing these MFM images. This research can be applied to data storage.
