Giant Magnetoresistive Biosensors for Time-Domain Magnetorelaxometry: A Theoretical Investigation and Progress Toward an Immunoassay. [PDF]

, 2017
Magnetorelaxometry (MRX) is a promising new biosensing technique for point-of-care diagnostics. Historically, magnetic sensors have been primarily used to monitor the stray field of magnetic nanoparticles bound to analytes of interest for immunoassays ...

Fermi Surface Nesting and Anomalous Hall Effect in Magnetically Frustrated Mn2PdIn

Advanced Functional Materials, EarlyView.
Mn2PdIn, a frustrated inverse Heusler alloy, showing electronic‐structure driven anomalous Hall effect with Weyl crossings, Fermi‐surface nesting and near‐zero magnetization ideal for low‐magnetization spintronics. Abstract Noncollinear magnets with near‐zero net magnetization and nontrivial bulk electronic topology hold significant promise for ...

Topotactic Phase Transition in Epitaxial La_0.7Sr_0.3MnO_3-δ Films Induced by Oxygen Getter Assisted Thermal Annealing. [PDF]

Small
The perovskite to brownmillerite topotactic phase transition in La0.7Sr0.3MnO3‐δ thin films is achieved through a simple and efficient thermal vacuum annealing that employs bulk aluminum as an active oxygen getter. STEM reveals surface segregation and cation redistribution, while EELS identifies distinct manganese oxidation states across different ...

Diamond Magnetometry of Meissner Currents in a Superconducting Film [PDF]

, 2016
We study magnetic field penetration into a thin film made of a superconducting niobium. Imaging of magnetic field is performed by optically detecting magnetic resonances of negatively charged nitrogen-vacancy defects inside a single crystal diamond ...

Atom-specific surface magnetometry [PDF]

Physical Review B, 1995
A powerful atom-specific surface magnetometry can be based on efficient measurements of magnetic dichroism in {ital l}{gt}0 core level photoemission. The temperature dependence M({ital T}) of the Fe(100) surface magnetization was obtained from the photoemission magnetic asymmetry of 3{ital p} core levels, providing the measure of the surface exchange ...

Pre-existing structural control on the recent Holuhraun eruptions along the Bárðarbunga spreading center, Iceland

Scientific Reports
The active rift zones in Iceland provide unique insight into the geodynamic processes of divergent plate boundaries. The geodynamics of Iceland are studied intensively, particularly, by geophysical methods sensitive to active and/or visible structures ...
