Magnetization and 57Fe hyperfine fields in Y2Fe17Z3-??(Z=H, C, or N) interstitial compounds
(American Physical Society, 1992)Measured magnetization and 57Fe hyperfine fields at T?_0 K for Y2Fe17 and Y2Fe17Z3-??, with Z=H, C, or N and ???_0.5, are analyzed to determine the influence of the interstitial atoms on the 3d magnetism. All are weak ... -
Magnetization and Temperature Dependence of the Mossbauer Spectrum Shift for an Insulator.
(American Physical Society, 1969)The results of a Mossbauer-effect study of HoFeO3 in the temperature range 99-875?K are presented. Special attention is paid to the shift of the center of the spectrum and its temperature dependence both above and below ... -
Magnetization of a Dy(Fe11Ti) single crystal
(American Physcial Society, 1990)Magnetization curves have been measured in the temperature range from 4.2 to 300 K along the [100], [110], and [001] directions of a Dy(Fe11Ti) single crystal in fields up to 7 T. The magnetic moment is along [100] below ... -
Magnetization of electrodeposited nickel: Role of interstitial carbon
(2006)The magnetization of nickel foils electrodeposited under different conditions was not usually found to differ significantly from that of the bulk (55.4?A?m2?kg?1). However, some galvanostatically deposited films from a ... -
Magnetization Process in Dilute Magnetic Oxides
(2010)Thin films of dilute magnetic oxides often exhibit high-temperature ferromagnetism with magnetization curves of the form M approximate to M-s tanh(H/H-0); the curves are practically anhysteretic and temperature-independent ... -
Magnetization processes in micron-scale (CoFe/Pt)(n) multilayers with perpendicular anisotropy: First-order reversal curves measured by extraordinary Hall effect
(2012)First-order reversal curves (FORCs) were recorded using the extraordinary Hall effect in micron-sized crosses of [Co90Fe10 (0.5?nm)/Pt (1.0?nm)] n multilayers with n?=?10, 20, and 50, which exhibit perpendicular magnetic ... -
Magnetization profile of magnetic impurities in graphene nanoribbons
(2011)The magnetic properties of graphene-related materials, and in particular, the spin-polarized edge states predicted for pristine graphene nanoribbons (GNRs) with certain edge geometries have received much attention recently ... -
Magnetization Reversal Behaviour of Planar Nanowire Arrays of Fe
(2013)Systematic investigations of magnetization behavior performed on planar arrays of 30 nm wide Fe-nanowires (NW) fabricated on oxidized step-bunched Si (111) templates reveal that the NW arrays exhibits an uniaxial anisotropy ... -
Magnetization States of All-Oxide Spin Valves Controlled by Charge-orbital Ordering of Coupled Ferromagnets
(2013)Charge-orbital ordering is commonly present in complex transition metal oxides and offers interesting opportunities for novel electronic devices. In this work, we demonstrate for the first time that the magnetization states ... -
Magneto-chiral anisotropy in charge transport through single-walled carbon nanotubes
(American Institute of Physics, 2002)Carbon nanotubes are chiral molecular objects and therefore exist in two forms that are each other?s mirror image. Many aspects of these fascinating new materials have recently been explored but their chirality has hardly ... -
Magneto-optic Kerr effect in a spin-polarized zero-moment ferrimagnet
(2018)The magneto-optical Kerr effect (MOKE) is often assumed to be proportional to the magnetization of a magnetically ordered metallic sample; in metallic ferrimagnets with chemically distinct sublattices, such as rare-earth ... -

Magnetocrystalline anisotropy of 3d-4f intermetallics: Breakdown of the linear theory.
(American Physical Society, 1994)Applicability of linear theory to magnetic anisotropy of 3d-4f intermetallics is investigated with particular reference to Sm2Fe17N3. A general quantitative criterion for the breakdown of the linear theory is established, ... -
