WebOct 15, 2024 · These paleointensities, which were measured from individual chondrules that carry thermoremanent magnetization (TRM) acquired before their accretion onto the LL parent body, provide evidence for the existence of a nebular magnetic field in the noncarbonaceous reservoir. WebThe QDM at the Harvard Paleomagnetics Laboratory has achieved spatial resolutions of ~1 µm with moment sensivities of less than 1x10-16 A m2, allowing it to image the magnetic fields generated by individual, single-domain ferromagnetic grains. These capabilities can be used to directly quantify natural or artificial magnetizations from grain ...
