Postselected amplification applied to atomic magnetometers

New Journal of Physics
Abstract We propose to embed the atomic magnetometer (AM) into an optical Mach–Zehnder interferometer (MZI). We analyze the effect of amplification of the Faraday rotation (FR) angle of the probe laser light, by properly postselecting the path-information state of the laser photons when passing through the MZI.

High‐Coercivity Nd2Fe14B/α‐Fe Nanocomposites With Ultrafine Nanocrystalline Structure via Zr‐Induced Synchronous Precipitation

Rare Metals, EarlyView.
ABSTRACT Nanocomposite permanent magnets with reduced rare‐earth content represent a promising class of materials for next‐generation high‐performance applications. However, asynchronous precipitation of soft and hard magnetic phases often results in grain size mismatch and limited coercivity.

Enhanced Low‐Frequency Microwave Absorption and Corrosion Resistance of FeSiAl Using Low‐Melting‐Point Glass Phase Coatings

Rare Metals, EarlyView.
ABSTRACT This study developed a FeSiAl@LMPGP composite material to address the demand for low‐frequency electromagnetic absorption. Through controllable heat treatment, FeSiAl particles and PbO nanoparticles self‐assembled into a high‐density Mott–Schottky heterointerface structure, which exhibited a significant built‐in electric field (BIEF) effect ...

Fermi Surface Structure Revealed by Quantum Oscillations in Half‐Heusler Semimetal LuAuSn

Rare Metals, EarlyView.
ABSTRACT The Fermi surface structure in the half‐Heusler semimetallic compound LuAuSn was systematically investigated using quantum oscillation studies of high‐quality single crystals and first‐principles calculations. Clear bulk quantum oscillation signals were observed for multiple complementary physical properties, including magnetization, Hall ...

Highly Anisotropic TbCo11Ti: Phase Evolution, Microstructure and Magnetic Properties

Rare Metals, EarlyView.
ABSTRACT Among the 1:12‐type compounds, TbCo11Ti stands out due to its high Curie temperature and pronounced magnetocrystalline anisotropy. However, its magnetic behavior at room temperature and its phase evolution process have not been clearly established.

System Design Considerations for Magneto‐Electrocatalysis of the Oxygen Evolution Reaction

Small, EarlyView.
Electrocatalytic water‐splitting can be controlled using a magnetic field. The commercial prospects are exciting, but the progress is stuck in the fundamental stage of research. Progress is stagnated by publications with conflicting results, incomplete analysis, and inconsistent experimental setups.
