Critical magnetization behaviors of the triangular and Kagome lattice quantum antiferromagnets

open access: yes, 2011
We investigate the $S=1/2$ quantum spin antiferromagnets on the triangular and Kagome lattices in magnetic field, using the numerical exact diagonalization.

Tunnel magnetoresistance of magnetic junctions with cubic symmetry of the layers [PDF]

open access: yesarXiv, 2009
A tunnel magnetic junction is considered with magnetic hard and magnetic soft layers of cubic symmetry. The magnetic switching is analyzed of the layers by a magnetic field perpendicular to the initial magnetizations. In such a situation, an additional peak of the TMR ratio appears at the magnetic field value lower substantially than the anisotropy ...

Complex Oxide‐metal Hybrid Metamaterials with Integrated Magnetic and Plasmonic Non‐noble Metal Nanostructures

open access: yesAdvanced Functional Materials, EarlyView.
A new alloy‐oxide vertically aligned nanocomposite (VAN) thin film with two immiscible non‐noble metal elements of Co and Cu embedded in BaTiO3 (BTO) matrix is designed and fabricated, which presents interesting magnetic, ferroelectric, and optical properties.

Magnetization Dissipation in Ferromagnets from Scattering Theory

open access: yes, 2011
The magnetization dynamics of ferromagnets are often formulated in terms of the Landau-Lifshitz-Gilbert (LLG) equation. The reactive part of this equation describes the response of the magnetization in terms of effective fields, whereas the dissipative ...

Vanadium Doped Magnetic MoS2 Monolayers of Improved Electrical Conductivity as Spin‐Orbit Torque Layer

open access: yesAdvanced Functional Materials, EarlyView.
Electrically conductive and room temperature magnetic atomically thin (≈0.8 nm) vanadium doped MoS2 (V‐MoS2) is demonstrated for its spintronic applications. Here, the spin transport at the interface of permalloy (Py) and high spin‐orbit coupling V‐MoS2 magnetic monolayers is shown.

Effects of Capping on the (Ga,Mn)As Magnetic Depth Profile

open access: yes, 2004
Annealing can increase the Curie temperature and net magnetization in uncapped (Ga,Mn)As films, effects that are suppressed when the films are capped with GaAs.

Deterministic Writing of Field‐Free and Unipolar Spin‐Transfer Torque Magnetic Random‐Access Memory

open access: yesAdvanced Functional Materials, EarlyView.
Deterministic unipolar‐switching STT‐MRAM with field‐free operation is experimentally demonstrated. The device features a compact 4F2 cell architecture using a diode as the access device and a single magnetic tunneling junction. Unlike conventional bipolar switching STT‐MRAM requiring a three‐terminal access transistor in the array, this design offers ...

Magnetostrictive hysteresis of TbCo/CoFe multilayers and magnetic domains

open access: yes, 2005
Magnetic and magnetostrictive hysteresis loops of TbCo/CoFe multilayers under field applied along the hard magnetization axis are studied using vectorial magnetization measurements, optical deflectometry and magneto optical Kerr microscopy.

Magnetic phase diagram copper metaborate CuB_2O_4 in magnetic field parallel c-axis: resonant, magnetic and magnetoelastic investigations [PDF]

open access: yesarXiv, 2005
The magnetic phase diagram in a single crystal of copper metaborate CuB_2O_4 in a magnetic field parallel to a tetragonal axis $c$ has been investigated. From the resonant, magnetic and magnetostrictive data the phase diagram of CuB_2O_4 on a plane ``temperature - magnetic field'' is constructed.

Living Microalgae‐Based Magnetic Microrobots for Calcium Overload and Photodynamic Synergetic Cancer Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
A magnetic microrobot fabricated by Spirulina platensis is proposed to accumulate in tumor regions and generate in situ high calcium concentration and sufficient oxygen. These characteristics of the microrobot present a strategy for triggering calcium overload therapy and chlorophyll‐mediated photodynamic therapy, and such combination resulted in a ...
