Dynamics of domain structure in magnetic multilayers

Spin Reorientation Transitions and Domain Structure in Magnetic Multilayers

Spin reorientation phase transitions and the evolution of the magnetic phases states arising during magnetization reversal of antiferromagnetic CoNiCu/Cu superlattice are studied using magneto-optical indicator film technique, accompanied by vector hysteresis loop measurements. The spinflop and nonsymmetric angle phases have been found and analyzed. It is shown that they arise due to the nuclea...

Magnetic force microscopy studies of the domain structure of CoÕPd multilayers in a magnetic field

We have measured the magnetic domain patterns in Co/Pd multilayers of varying thickness using magnetic force microscopy in the presence of an external magnetic field applied perpendicular to the multilayers. We find that the domain patterns evolution is in qualitative agreement with existing theories for single layer thin films. Our results are in reasonable agreement with a theoretical model o...

Study of Magnetic Domain Structure in Co(Fe)/Pd Multilayers using Off-axis Electron Holography

Magnetic nanostructures that are magnetized perpendicular to their surface are central to many developing technologies, including spintronics devices and patterned media, because of the requirement to maintain thermal stability as device dimensions are scaled further into the nanoscale. Multilayer or superlattice materials such as Co(Fe)/Pd are convenient for these applications due to their hig...
