Further evidence for early lunar magnetism from troctolite 76535 [PDF]

open access: yes, 2017
The earliest history of the lunar dynamo is largely unknown and has important implications for the thermal state of the Moon and the physics of dynamo generation.

Evidence for Widespread Remagnetizations in South America, Case Study of the Itararé Group Rocks From the State of São Paulo, Brazil

open access: yesFrontiers in Earth Science, 2018
Paleomagnetism of South American Jurassic/Cretaceous rocks has been troubled by elongated distributions of poles which has led to contrasting interpretations.

Investigating the utility of a high-temperature Thellier-style paleointensity experimental protocol

open access: yesEarth, Planets and Space, 2021
High-quality data are vital to the research field of paleointensity, which has long suffered from poor-quality and/or sparse data. Previous paleointensity work has established that repeatedly heating specimens increases the opportunity for thermochemical

Exchange interactions in transition metal oxides: The role of oxygen spin polarization [PDF]

open access: yes, 2017
Magnetism of transition metal (TM) oxides is usually described in terms of the Heisenberg model, with orientation-independent interactions between the spins.

The magnetic record of the Late Glacial-Holocene transition in sediments from Grandfather Lake (Southwest Alaska)

open access: yesGeofísica Internacional, 1999
Las mediciones preliminares de propiedades magnéticas en muestras de un núcleo de 8.5 m. de longitud del lago Granfather (suroeste de Alaska), indican que la magnetización remanente de estos sedimentos reside en magnetita con comportamiento de ...

Variations in the Magnetic Properties of Meteoritic Cloudy Zone

open access: yesGeochemistry, Geophysics, Geosystems, 2020
Iron and stony‐iron meteorites form the Widmanstätten pattern during slow cooling. This pattern is composed of several microstructures whose length‐scale, composition and magnetic properties are dependent upon cooling rate.

Paleomagnetism, rock magnetism and geochemical aspects of early Cretaceous basalts of the Paraná Magmatic Province, from Misiones, Argentina [PDF]

open access: yes, 2006
The basalts of the Posadas Formation were extruded during the huge continental volcanism that affected the Parana Basin in the Lower Cretaceous. We have carried out a paleomagnetic and rock-magnetic study on samples collected along a basalt outcrop ...

Rock magnetism and soil magnetic susceptibility

open access: yesAgrochemistry and Soil Science, 2021
Information support of modern agriculture and ecology forms a demand for ever higher requirements for efficiency and density of the sampling network. This fact determines the spread of high-performance methods of soil research, among which are magnetometric ones. However, these methods have a number of limitations associated with the existence in soils

Coexistence of spin glass and ferroelectricity in highly ordered Bi2FeMnO6 epitaxial thin film [PDF]

open access: yes, 2016
Highly ordered Bi2FeMnO6 epitaxial thin films have been successfully grown on SrTiO3 substrate. Both synchrotron X-ray reciprocal space mapping and high resolution transmission electron microscopy confirmed the alternative alignment of Fe and Mn along ...

Magnetic Vortex States in Small Octahedral Particles of Intermediate Titanomagnetite

open access: yesGeochemistry, Geophysics, Geosystems, 2018
Fine particles of titanomagnetites (Fe3‐xTixO4, x > 0.5) in the pseudo‐single‐domain (PSD) size (0.5–20 μm) are important carriers of natural remanent magnetization in basalts.
