Magnetic relaxation measurements of exchange biased (Pt/Co) multilayers with perpendicular anisotropy
Magnetic relaxation measurements were carried out by magneto-optical Kerr effect on exchange biased (Pt/Co)5/Pt/FeMn multilayers with perpendicular anisotropy. In these films the coercivity and the exchange bias field vary with Pt spacer thickness, and have a maximum for 0.2 nm. Hysteresis loops do not reveal important differences between the reversal for ascending and descending fields. Relaxa...
متن کاملFormation of an anisotropy lattice in Co/Pt multilayers by direct laser interference patterning
Formation of an anisotropy lattice in Co/ Pt multilayers by direct laser interference patterning" (2006). Roger Kirby Publications. 2. We report on the use of direct laser interference patterning to form an " anisotropy " lattice in Co/ Pt thin film multilayers. Co/ Pt multilayers have been extensively studied and, for the compositions studied here, are characterized by strong perpendicular mag...
متن کاملEvolution of magnetic domain reversal with temperature in Co ÕPt multilayers observed by magneto-optical Kerr imaging
The evolution of magnetic domain structures with temperature during magnetic reversal in Co 4 Å /Pt tPt multilayers with perpendicular anisotropy has been investigated using magneto-optical Kerr imaging. Relatively large Pt layer thicknesses tPt=43 and 63 Å are chosen for this study because the interlayer coupling strength in the multilayers varies from weak at room temperature to strong at low...
متن کاملNovel (Pt/Co/Pt/Ni) multilayers for magneto-optical recording media
The sputter deposited ~Pt/Co/Pt/Ni! multilayer films were studied as possible alternative low Curie temperature multilayers for magneto-optical recording. The Curie temperatures of these multilayers were found to be between 150 and 300 °C, which are much lower than those of Co/Pt multilayers or ~Co,Ni!/Pt multilayers. The coercivities of these multilayers were between 450 and 800 Oe. The Kerr s...
متن کاملMagnetic reversal of perpendicularly-biased Co/Pt multilayers
We have investigated the magnetic reversal behavior of [(Co/Pt)4Co/CoO]N multilayers that are exchange biased perpendicular to the film plane. We find clear differences in the nucleation properties of the reverse domains of the ascending and descending branches of the hysteresis loops. However, the evolution of the reverse domains, once nucleated, are symmetric to positive and negative field sw...
