Potbellies, wasp-waists, and superparamagnetism in magnetic hysteresis
TL;DR: In this paper, the authors discuss results of numerical simulations using the simplest of systems, the single-domain/superparamagnetic (SD/SP) system, and demonstrate that wasp-waisting and potbellies can be easily generated from populations of SD and SP grains.

Magnetic Properties of Rocks and Minerals
TL;DR: In this article, an updated collation of magnetic parameters of rocks and minerals for geologists, geochemists, and geophysicists is presented, and best-fit equations have been provided for some of the displayed ata so that interpolations can be made easily.

Anisotropy of magnetic remanence: A brief review of mineralogical sources, physical origins, and geological applications, and comparison with susceptibility anisotropy
TL;DR: In the absence of a magnetic field, the magnetic fabric of rocks and sediments is most commonly characterized in terms of the anisotropy of low-field magnetic susceptibility (AMS) as mentioned in this paper.
Journal ArticleDOI
On the superparamagnetic—stable single domain transition for magnetite, and frequency dependence of susceptibility
TL;DR: In this paper, the authors reviewed the nature of the superparamagnetic stable single domain transition and showed that the change of AC susceptibilities with grain size (or temperature) at the SP-SSD boundary is more gradual than commonly assumed.

A Mechanism of Magnetic Hysteresis in Heterogeneous Alloys
Edmund C. Stoner,E. P. Wohlfarth +1 more
TL;DR: In this paper, the effect of shape anisotropy on magnetization curves was studied for the case of ellipsoidal spheroids of revolution (e.g., ellipses of revolution).

The physical principles of rock magnetism
TL;DR: A review of the physical principles of rock magnetism can be found in this article, which is of modest length and meets the dual requirements of being comprehensible to geologists and satisfying to physicists Even a very small percentage of a ferromagnetic mineral, such as magnetite, in a rock masks the paramagnetic and diamagnetic properties of the other minerais.

Theoretical single-domain grain size range in magnetite and titanomagnetite
TL;DR: In this paper, a theoretical model of single-domain (SD) grain sizes is applied to magnetite and titanomagnetite, where transition to a two-domain configuration takes place at the SD threshold d0.

A new rock‐magnetic approach to selecting sediments for geomagnetic paleointensity studies: Application to paleointensity for the last 4000 years
TL;DR: In this paper, the authors evaluate the DRM/ARM ratio of detrital remanent magnetization to anhysteretic remanent magnetic magnetization (DRM/ARM) for sediment samples to measure relative geomagnetic paleointensity.
