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.

Membrane optomechanical magnetometer

Optics Express
We demonstrate an optomechanical magnetometer where a high-Q membrane mechanical resonator responds to the magnetic-field-induced deformations of two magnetostrictive materials and is monitored by a two-beam Fabry-Perot cavity. The magnetometer enables simultaneous measurements of DC and AC magnetic fields and can recognize the direction of a two ...
