Magnetotactic bacteria contain chains of magnetically interacting crystals (magnetosome
crystals), which they use for navigation (magnetotaxis). To improve magnetotaxis efficiency …

Although ferrimagnetic material appears suitable as a basis of magnetic field perception in
animals, it is not known by which mechanism magnetic particles may transduce the …

The characterization of individual magnetic components in sediments and sedimentary
rocks is difficult, as these natural materials are often a complex mixture of magnetic mineral …

Variations in magnetic properties of buried soils can be used to reconstruct past climatic
conditions during paleosol formation. Most methods, however, are based on comparisons …

Plots of the first‐order reversal curve (FORC) function are used to characterize ferromagnetic
particles in rocks. The function is based on classical Preisach theory, which represents …

Various magnetic parameters are in common use for estimating the grain size of magnetic
particles. Among these, the ratio of the intensity of anhysteretic remanent magnetization …

The critical size for stable single‐domain (SD) behavior has been calculated as a function of
grain elongation for magnetite grains using a numerical micromagnetic algorithm …

Large impact craters on Earth are associated with prominent magnetic anomalies, residing
in magnetite of the shocked target rocks and impactites. Shock experiments on magnetite …

Tiny basaltic samples containing finely grained titanomagnetite with Curie temperature less
than 100° C were heated in air in weak field (25–100μT) at temperatures between 400° C …

Abstract Kamacite particles (Fe–Ni, Ni< 5 per cent), are very common in extra-terrestrial
materials, such as meteorites. It is normally assumed that for kamacite particles to be reliable …
