A New Highly Anisotropic Rh-Based Heusler Compound for Magnetic Recording
(2020)
The development of high-density magnetic recording media is limited by superparamagnetism in very small ferromagnetic crystals. Hard magnetic materials with strong perpendicular anisotropy offer stability and high recording ...
The magnetic and magnetoresistance properties of ultrathin magnetite films grown on MgO substrate
(AMERICAN INSTITUTE OF PHYSICS, 2006)
We report on the properties of ultrathin (2, 4, 6, and 8?nm) epitaxial films of magnetite, Fe3O4, grown on MgO (100). Atomic force microscopy image and V-I curves suggest that the films at this thickness are still continuous. ...
Ab initio calculation of the biasdependent transport properties of Mn12 molecules
(2009)
The bias-dependent transport properties of a device constructed by sandwiching a Mn
12
single molecule
magnet between gold electrodes are investigated within an
ab initio
framework combining the nonequilibrium
Green?s ...
Generation, characterisation and solidification of crystalline microfoams
(Trinity College (Dublin, Ireland). School of Physics, 2008)
This study is centered around the spontaneous ordering of equally sized microbubbles on
top of a liquid pool, forming wet crystalline microfoams. This type of ordering was firstly
observed by Bragg and Nye in 1947 and only ...
Antiferromagnetic interlayer exchange coupling between Fe3O4 layers across a nonmagnetic MgO dielectric layer
(2008)
We have investigated the interlayer exchange coupling between the epitaxial spinel Fe3O4 layers across an insulating nonmagnetic MgO spacer. The epitaxial structure used for these investigations was Fe3O4 (10?nm)/MgO ...
Understanding the Physical Nature of Coronal "EIT Waves"
(2017)
For almost 20 years the physical nature of globally propagating waves in the solar corona (commonly called “EIT waves”) has been controversial and subject to debate. Additional theories have been proposed over the years ...
Magnetism of (Zn,Co)O thin films probed by x-ray absorption spectroscopies
(2008)
We report on the electronic and magnetic properties of Co-doped ZnO thin films investigated by x-ray absorption spectroscopies and element selective magnetometry. For a low Co concentration (around 5%), we evidence a ...
Two-dimensional Förster resonant energy transfer in a mixed quantum dot monolayer: Experiment and theory
(2009)
Energy transfer in monolayers of CdTe quantum dots (QDs), comprised of QDs of two different sizes, has been investigated. Förster resonant energy transfer (FRET) from QD donors to QD acceptors was observed and characterized ...
High inverted tunneling magnetoresistance in MgO - based magnetic tunnel junctions
(2007)
Inverted tunneling magnetoresistance, where resistance decreases as the free layer in a magnetic tunnel junction flips its direction of magnetization after saturation, has been observed at zero bias in magnetic tunnel ...
