Vortex guide under a Lorentz force.

AiBi Revista de Investigación, Administración e Ingeniería, 2020
In the present work we study the effect that the metallic quality of the contacts by which an external current is applied, has on the magnetic properties of a superconducting sample.

A Close Look at the Local Structure of Functional Polymers: The Example of Poly(Vinylidene Fluoride)

Advanced Functional Materials, EarlyView.
To accurately develop structure‐property relationships in functional macromolecules, it is increasingly important to consider the local chain arrangement in addition to long‐range order. It is demonstrated in the case of poly(vinylidene fluoride) that solid‐state nuclear magnetic resonance (NMR) spectroscopy can provide detailed insights into the local

Temperature-dependent magnetization in diluted magnetic semiconductors

, 2002
We calculate magnetization in magnetically doped semiconductors assuming a local exchange model of carrier-mediated ferromagnetic mechanism and using a number of complementary theoretical approaches. In general, we find that the results of our mean-field

Control of Ferromagnetism of Vanadium Oxide Thin Films by Oxidation States

Advanced Functional Materials, EarlyView.
The nonstoichiometric VOx exhibits a distinct ferromagnetic hysteresis loop and demonstrates a high magnetic susceptibility (χ=dMdH$ = \frac{{dM}}{{dH}}\;$∼10). Micromagnetic simulations show the results of the “partial volume fraction ferromagnetic phase model” for VOx/Co/Pt structure.

Discovery of an Intrinsic Antiferromagnetic Semiconductor EuSc2Te4 With Magnetism‐Driven Nonlinear Transport

Advanced Functional Materials, EarlyView.
EuSc₂Te₄, an antiferromagnetic semiconductor, exhibits a nonlinear Hall effect (NLHE) characterized by quadratic current–voltage behavior. Combined experimental and theoretical studies reveal that this NLHE is linked to its antiferromagnetism and involves contributions from the quantum metric.

Current-induced torques in textured Rashba ferromagnets

, 2012
In systems with small spin-orbit coupling, current-induced torques on the magnetization require inhomogeneous magnetization textures. For large spin-orbit coupling, such torques exist even without gradients in the magnetization direction.

Spin‐Selective Anisotropic Magnetoresistance Driven by Chirality in DNA

Advanced Functional Materials, EarlyView.
It is shown that magnetoresistance (MR) measurements carried out as a function of angular dependence between the magnetic field and a chiral (DNA) interface provide a valuable new insight into the charge transport mechanism associated with the chiral‐induced spin selectivity (CISS) effect.
