The importance of clays in speleothem magnetic remanence acquisition [PDF]
Scientific ReportsSpeleothems are promising recorders of paleosecular variation of the Earth’s magnetic field, but ambiguities remain about the physical processes active during remanence acquisition.

Microscopic magnetic-field imaging of a single lunar dust grain [PDF]
Fundamental ResearchThe origin of lunar magnetic anomalies—whether remnants of an ancient core dynamo or impact-induced magnetizations—remains debated due to a critical observational gap linking microscopic magnetic carriers to macroscopic orbital measurements. Conventional

, 1997 Rock Magnetism, first published in 1997, is a comprehensive treatment of fine particle magnetism and the magnetic properties of rocks. Starting from atomic magnetism and magnetostatic principles, the authors explain why domains and micromagnetic structures form in ferromagnetic crystals and how these lead to magnetic memory in the form of thermal ...

Micromagnetic Tomography for Paleomagnetism and Rock-Magnetism. [PDF]
J Geophys Res Solid Earth, 2021 Abstract Our understanding of the past behavior of the geomagnetic field arises from magnetic signals stored in geological materials, e.g., (volcanic) rocks. Bulk rock samples, however, often contain magnetic grains that differ in chemistry, size, and shape; some of them record the Earth's magnetic field well, others are unreliable ...

Magnetic Properties of Plant Ashes and Their Influence on Magnetic Signatures of Fire in Soils
Frontiers in Earth Science, 2021 Fires are an integral part of many terrestrial ecosystems and have a strong impact on soil properties. While reports of topsoil magnetic enhancement after fires vary widely, recent evidence suggests that plant ashes provide the most significant source of
