Angular dependence of the magnetic properties of cylindrical nanostructures with wire–tube morphology
(2014)
We have investigated the angular dependence of the magnetic properties of cylindrical nanostructures comprised of a pair of nanotube and nanowire segments. We compared the magnetic behavior of these structures with the ...
Universal Pinning Energy Barrier for Driven Domain Walls in Thin Ferromagnetic Films
(American Physical Society, 2016-07-29)
We report a comparative study of magnetic field driven domain wall motion in thin films made of different magnetic materials for a wide range of field and temperature. The full thermally activated creep motion, observed ...
Gapless-excitation induced resistivity in ferromagnetic layers

Stochastic Current-Induced Magnetization Switching in a Single Semiconducting Ferromagnetic Layer
(American Physical Society, 2014-01-14)
We show experimental evidence of magnetization switching in a single (Ga,Mn)(As,P) semiconducting ferromagnetic layer, attributed to a strong reduction of the magnetization and the anisotropy due to current injection. The ...
Inverse transition in the dipolar frustrated Ising ferromagnet: The role of domain walls
(American Physical Society, 2014-12)
We present a theoretical study aimed at elucidating the origin of the inverse symmetry-breaking transitionobserved in ultrathin magnetic films with perpendicular anisotropy. We study the behavior of the dipolar frustratedIsing ...
Artificial chemical and magnetic structure at the domain walls of an epitaxial oxide
(Nature Publishing Group, 2014-11)
Progress in nanotechnology requires new approaches to materials synthesis that make it possible to control material functionality down to the smallest scales. An objective of materials research is to achieve enhanced control ...
Spin wave eigenmodes in transversely magnetized thin film ferromagnetic wires
(Amer Physical Soc, 2015)
We report experimental and theoretical studies of spin wave eigenmodes in transversely magnetized thin film Permalloy wires. Using broadband ferromagnetic resonance technique, we measure the spectrum of spin wave eigenmodes ...
Nanometric alternating magnetic field generator
(2017)
In this work we introduce an alternating magnetic field generator in a cylindrical nanostructure. This field appears due to the rotation of a magnetic domain wall located at some position, generating a magnetic region that ...
Speed of field-driven domain walls in nanowires with large transverse magnetic anisotropy
(2015)
Recent analytical and numerical work on field-driven domain wall propagation in nanowires and thin films has shown that for large transverse anisotropy and sufficiently large applied fields the Walker profile becomes ...
