Magnetic noise in structured hard magnets
(2010)The anomalous Hall effect of wires patterned from ?Co90Fe10=Pt?n multilayers, with 10 n 50, is used to determine the magnetization process in a small volume of maze domains. Time-independent 1=f noise appears in ... -
Magnetic order and magnetotransport in half-metallic ferrimagnetic MnyRuxGa thin films
(2021)The ruthenium content of half-metallic Mn2RuxGa thin films, with a biaxially strained inverse Heusler structure, controls the ferrimagnetism that determines their magnetic and electronic properties. An extensive study of ... -
Magnetic Properties of Exchange-Biased [Co/Pt](n) Multilayer With Perpendicular Magnetic Anisotropy
(2010)Perpendicular exchange-biased [Co/Pt](3)/Co(t(Co))/IrMn and IrMn/Co(t(Co))/Pt/[Co/Pt](3) multilayers have been fabricated, changing the thickness (t(Co)) of the cobalt that is next to the IrMn layer. The crystal structure, ... -
Magnetic properties of iron-rich Fe-Sc glasses
(American Physical Society, 1989)Amorphous FexSc100-x alloys with x=89, 90, and 91, prepared by melt spinning, exhibit a single sharp spin-freezing transition at 100 3 K to an asperomagnetic state. The average Fe57 hyperfine field at 4.2 K is 22.7 T. ... -
Magnetic properties of iron-rich Fe-Zr glasses
(American Physcial Society, 1987)A systematic study of the magnetic properties of melt-spun amorphous FexZr100-x alloys with 88?x?93 using Mossbauer and magnetization measurements has established the magnetic phase diagram. The ordering temperature Tc ... -
Magnetic properties of mechanically-alloyed Sm-Co nanophase hard magnets
(IEEE, 2001)Highly coercive Sm14Co86 powders were prepared by mechanical alloying with a view to enhance the high temperature magnetic properties by optimizing the annealing conditions. The powders were annealed in quartz tubes with ... -
Magnetic properties of planar nanowire arrays of Co fabricated on oxidized step-bunched silicon templates
(NANOTECHNOLOGY, 2012-06-15)Planar nanowire (NW) arrays of Co grown on oxidized step-bunched Si(111) templates exhibit room temperature ferromagnetic behaviour for wire widths down to 25 nm. Temperature and thickness dependent magnetization studies ... -
Magnetic properties of the Co/Alq(3) interface
(2011)A method is described for measuring the magnetic integrity of ferromagnetic/organic interfaces that involves measuring the magnetic moment per unit area of bilayers with different ferromagnet thicknesses. The method is ... -
Magnetic properties of the magnetoelectric compound Cu2OSeO3: Magnetization and 77Se NMR study
(2011)We present magnetization and 77Se Nuclear Magnetic Resonance (NMR) measurements in single crystals of the magneteoelectric compound Cu2OSeO3. The temperature and field dependence of the magnetization suggest a ferrimagnetic ... -
Magnetic Properties of Ultrathin Magnetite Films Grown by Molecular Beam Epitaxy
(IEEE-INSTITUTE OF ELECTRICAL AND ELECTRONIC ENGINEERS INC, 2008)Magnetic properties as a function of film thickness (2-55 nm) for magnetite (Fe3O4) thin films grown on MgO (100) substrates show that the small thickness films (les 5 nm) are ferromagnetic and possess magnetization values ... -
Magnetic Resonance Imaging in Ophthamology
(2012)Imaging the eye with magnetic resonance imaging (MRI) has proved difficult due to the eye?s propensity to move involuntarily over typical imaging timescales, obscuring the fine structure in the eye due to the resulting ... -
Magnetic reversal and pinning in a perpendicular zero-moment half-metal
(2021)Compensated ferrimagnets are promising materials for fast spintronic applications based on domain-wall motion as they combine the favorable properties of ferromagnets and antiferromagnets. They inherit from antiferromagnets ... -
