Layered Spin‐Crossover Metal‐Organic Frameworks for Light‐Induced Control of Two‐Dimensional Quantum Materials

Advanced Materials, EarlyView.
Spin‐crossover metal‐organic frameworks (SCO‐MOFs) provide a route to control the electronic and magnetic properties of two‐dimensional quantum materials. By integrating a layered SCO‐MOFs with graphene, CrSBr, and NbSe2 nanodevices, thermally and light induced spin transitions induce strain that reversibly modulates charge transport, magnetic memory ...

Grazing Incidence X-ray Scattering from Magnetic Thin Films and Nanostructures [PDF]

, 2009
Grazing incidence scattering of synchrotron x-rays has been used to characterize the structure of magnetic thin films and periodic nanostructures. The combined metal and metal oxide films have been chosen to clarify the effects of growth processing ...

Anomalous Hall magnetoresistance in a ferromagnet

, 2018
The anomalous Hall effect, observed in conducting ferromagnets with broken time-reversal symmetry, offers the possibility to couple spin and orbital degrees of freedom of electrons in ferromagnets.

Thermodynamics of Concomitant Charge‐Transfer, Antiferromagnetic, and Isostructural Phase Transitions in Barocaloric ACu3Fe4O12 Quadruple Perovskites

Advanced Science, EarlyView.
A copper‐iron charge transfer instability drives concomitant electronic, magnetic, and isostructural phase transitions in ACu3Fe4O12${\rm ACu}_3{\rm Fe}_4{\rm O}_{12}$, with an inverse barocaloric effect. A minimal Landau theory ties these thermodynamic signatures together, revealing a pressure‐independent transition entropy with comparable charge and ...

Current scaling of the magnetoresistance peaks in the microwave radiation induced magnetoresistance oscillations

Scientific Reports
We study the current scaling of the oscillatory magnetoresistance peak height in microwave induced magnetoresistance oscillations, over the temperature range $$0.35 \le T \le 1.25\,\,{\rm K}$$ , by examining the change in response observed under a ...

The tunneling magnetoresistance current dependence on cross sectional area, angle and temperature

AIP Advances, 2015
The magnetoresistance of a MgO-based magnetic tunnel junction (MTJ) was studied experimentally. The magnetoresistance as a function of current was measured systematically on MTJs for various MgO cross sectional areas and at various temperatures from 7.5 ...

Magnetoelectric Nanoparticle‐Based Wireless Brain–Computer Interface: Underlying Physics and Projected Technology Pathway

Advanced Science, EarlyView.
Magnetoelectric nanoparticles (MENPs) enable fully wireless, minutely invasive neuromodulation, and potentially neural recording, by converting magnetic into electric and, conversely, electric into magnetic fields, respectively, at high spatiotemporal resolution.

A systematic approach to multiphysics extensions of finite-element-based micromagnetic simulations: Nmag

, 2007
Extensions of the basic micromagnetic model that include effects such as spin-current interaction, diffusion of thermal energy or anisotropic magnetoresistance are often studied by performing simulations that use case-specific ad-hoc extensions of widely
