Design, realization and application of a vector atomic magnetometer

, 2014
Plusieurs technologies de magnétomètres atomiques ont été développées depuis les années 60. Afin d’obtenir une technologie capable de mesurer des champs magnétiques inférieurs à 50 nT et compatible avec notre magnétomètre scalaire isotrope, nous avons du

Dislocation‐Mediated Lattice Distortion and Griffiths Phase Behavior in Melt‐Spun Ni2MnSb Ribbons

Advanced Science, EarlyView.
This figure illustrates how melt‐spinning introduces dislocations into Ni2MnSb Heusler alloys. TEM images reveal local lattice distortions and associated strain fields surrounding dislocations at a representative wheel speed. As wheel speed increases, these distortions promote the formation of ferromagnetic clusters within a paramagnetic matrix ...

A Wireless 3D Magneto‐Mechanical Stimulation Platform Drives In Situ Chondrogenic Commitment of Endogenous MSCs

Advanced Science, EarlyView.
An intracellular magneto‐mechanical platform utilizing MSC‐targeted nanomotors is developed. After intra‐articular delivery, these nanomotors target endogenous BMSCs and are actuated within lysosomes to execute trans‐planar rotational‐bouncing motions under a rotating‐fluctuating 3D magnetic field, generating amplified mechanical stimulation.

3D‐Printed Magnetoelectronics for Interactive Appliances and Self‐Aware 4D‐Printed Mechatronics

Advanced Science, EarlyView.
3D‐printed magnetoelectronics integrate high‐performance magnetic field sensing directly into complex structural components. Flexible spring and cross‐shaped sensors exhibit giant magnetoimpedance and 3D Hall sensing for vector field reconstruction. Applications include smart‐home switches, robotic joysticks, volumetric magnetometers, and self‐aware 4D‐

Atomically Modulating Competing Exchange Interactions in Centrosymmetric Skyrmion Hosts GdRu2X2 (X = Si and Ge)

Advanced Electronic Materials, EarlyView.
Our work bridges the gap between skyrmion discovery and material design by demonstrating how atomic‐scale control of exchange interactions enables tunable skyrmion phase transitions in centrosymmetric magnetic metals. ABSTRACT Magnetic skyrmions are topologically protected spin states that hold promise for shaping the future of electronics.

Large Anomalous Nernst Effect in Disordered CoPt Thin Films for Planar Thermoelectric Sensing

Advanced Electronic Materials, EarlyView.
Disordered CoPt thin films exhibit a large anomalous Nernst effect with strong dependence on Pt concentration. The transverse thermoelectric response reaches 3.22 µV K−1 near equiatomic composition and an ANE sensitivity of 0.3 µm A−1. The results reveal that composition‐controlled microstructure in sputtered CoPt alloys provides an effective route for

Discovery of an Ideal HgO12 Icosahedron and Magnetodielectric Coupling in HgCu3Ti4O12

Advanced Electronic Materials, EarlyView.
HgCu3Ti4O12, an A‐site‐ordered quadruple perovskite with a perfectly regular HgO12 coordination, has been synthesized for the first time using high‐pressure methods. The material shows antiferromagnetic ordering at 31 K together with an intrinsic dielectric anomaly, implying possible magnetodielectric coupling.
