Effects of Ag pinning layers on the magnetic properties of Fe/Pt multilayer films

چکیده
Tetragonal L10 ordered Fe/Pt multilayers were prepared by molecular-beam epitaxy on Pt-buffered MgOs001d substrates at 500 °C. An ultrathin Ag s0.5 nmd layer was symmetrically inserted into fFe/Ptg bilayers with different periods to introduce defects or pinning sites at the interfaces of Ag and Fe/Pt bilayers. The effects of Ag pinning layers in the Fe/Pt multilayers have been studied. The insertion of Ag pinning layers effectively reduced the size of magnetic domains. The distribution of angular dependent coercivity of Fe/Pt multilayers with inserted Ag pinning layers between zero and ten periods, indicates a tendency of the domain-wall motion behavior to be weakened but nucleation mode enhanced. © 2005 American Institute of Physics. fDOI: 10.1063/1.1855491g

X-ray diffraction measurements were performed on Co?Pt1-?/Pd, Co/Pd, Co/Fe, and Co/W multilayer samples with different structures, such as Co?Pt1-? alloy layer composition ?, bilayer thickness, and number of bilayers. Multilayer samples were made by magnetron sputtering in a chamber with multi-parallel guns and a position controllable substrate. Co?Pt1-? alloy layers were deposited by cosputter...

Fe/Pt/Cu]18 multilayer films with different Cu thicknesses were prepared on thermally oxidized Si (111) substrates at room temperature using dcand rf-magnetron sputtering. The magnetic properties and microstructure of [Fe/Pt/Cu]18 multilayer films annealed at various temperatures have been investigated. Compared with pure [Fe/Pt]18 multilayer films low-temperature ordering and (001) orientation...
متن کاملPermanent-Magnet Properties of Thermally Processed FePt and FePtâ•fiFe Multilayer Films
FePt single-layer and FePt–Fe multilayer thin films are prepared by magnetron sputtering. By varying the Pt content, FePt, Fe3Pt, or a mixture of FePt and Fe3Pt can be obtained in Fe–Pt single layers. In annealed FePt–Fe multilayers, the coercivities decrease with the introduction of Fe layers compared to FePt single layers, while the magnetization increases. The single-phase behavior of the hy...
متن کاملMagnetic Properties of Fe/Cu Multilayers Prepared Using Pulsed-Current Electrodeposition
[Fe (tFe) nm/Cu (tCu) nm]N multilayer films were prepared using pulsed-current electrodeposition method. The role of the pulsed-current deposition and Fe and Cu layer thicknesses on the magnetic properties was investigated. The microstructure of the multilayer films is dependent on the thicknesses of both the Fe and Cu layers. The saturation magnetization of the multilayers strongly correlated ...
متن کاملMechanisms of periodic pinning in superconducting thin films
We studied the changes in the superconducting properties of Nb films due to an array of Ni dots used as collective pinning sites. To determine the pinning mechanism, thin Ag layers of varying thicknesses were deposited on the Ni dots prior to the Nb film deposition. The Ag deposited on the pinning dots has little effect on the collective pinning phenomena, which implies that the main pinning me...
