Magnetic Field Signatures of Tropospheric and Thermospheric Lamb Modes Triggered by the 15 January 2022 Tonga Volcanic Eruption

Geophysical Research Letters, 2023
Intense eruptions of the Tonga volcano activated prominent traveling atmospheric disturbances (TADs) at 04:05UT on 15 January 2022. Himawari‐8 satellite images depict that TADs of the tropospheric Lamb wavefront propagate with a speed of 315 m/s and ...

Electrical Tuning of Ferrimagnetic Spin Alignment Angle and Compensation Temperature in Pt/IrMn3/CoGd Multilayers

Advanced Functional Materials, EarlyView.
Spin‐orbit torque controls the Néel vector of antiferromagnetic IrMn3, which selectively exchange‐couples with spins of Co only in the ferrimagnetic CoGd. This selective interfacial pinning induces the non‐collinear spiral spin configuration, leading to a non‐uniform distribution of local compensation temperature along the film thickness, and enabling ...

Stronger Evidence of a Subsurface Ocean Within Callisto From a Multifrequency Investigation of Its Induced Magnetic Field

AGU Advances
The magnetometer investigation of the Galileo mission used the phenomenon of magnetic induction to produce the most compelling evidence that subsurface oceans exist within our solar system. Although there is high certainty that the induced field measured

Anisotropic Phonon Dynamics and Directional Transport in Actinide Van der Waals Semiconductor Uranium Triselenide

Advanced Functional Materials, EarlyView.
USe3 is introduced as an actinide van der Waals semiconductor that mirrors the quasi‐one‐dimensional physics of transition‐metal trichalcogenides. Polarization‐resolved Raman spectroscopy on exfoliated flakes maps strong in‐plane phonon anisotropy and strain‐tunable mode shifts.

Will we find Martian lightning via Schumann resonances?

Frontiers in Astronomy and Space Sciences, 2023
Schumann resonances are electromagnetic resonances generally associated with lightning. If they exist on Mars, Schumann resonances are expected to resonate within the ionospheric cavity at a fundamental frequency of 7–14 Hz.
