The cooling‐rate effect on microwave archeointensity estimates [PDF]
Geophysical Research Letters, 2013 AbstractNew microwave (MW) paleointensity data on historical bricks from Northeast Brazil presented a bias toward higher fields when compared to previous cooling‐rate corrected double‐heating paleointensity estimates; the same relates to the previously reported values for pottery from Southwestern Pacific islands. A simple theoretical approach suggests

Rapid Intensity Decrease During the Second Half of the First Millennium BCE in Central Asia and Global Implications [PDF]
, 2022 Recent paleomagnetic studies have shown that important short-lived intensity fluctuations occurred during the first millennium BCE. However, the knowledge of the spatial and temporal extension of these features is still limited by the scarce availability

Reconstructing the geomagnetic field in west africa: first absolute intensity results from Burkina Faso [PDF]
, 2017 We present absolute geomagnetic intensities from iron smelting furnaces discovered at the metallurgical site of Korsimoro, Burkina Faso. Up to now, archaeologists recognized four different types of furnaces based on different construction methods ...

The impact of geomagnetic spikes on the production rates of cosmogenic 14C and 10Be in the Earth's atmosphere [PDF]
, 2015 We seek corroborative evidence of the geomagnetic spikes detected in the Near East ca. 980 BC and 890 BC in the records of the past production rates of the cosmogenic nuclides 14C and 10Be.

Epsilon iron oxide: Origin of the high coercivity stable low Curie temperature magnetic phase found in heated archeological materials [PDF]
, 2017 The identification of epsilon iron oxide (-Fe2O3) as the low Curie temperature high coercivity stable phase (HCSLT) carrying the remanence in heated archeological samples has been achieved in samples from two archeological sites that exhibited the ...

Solar activity during the Holocene: the Hallstatt cycle and its consequence for grand minima and maxim [PDF]
, 2016 Cosmogenic isotopes provide the only quantitative proxy for analyzing the long-term solar variability over a centennial timescale. While essential progress has been achieved in both measurements and modeling of the cosmogenic proxy, uncertainties still ...

One Hundred Thousand Years of Geomagnetic Field Evolution
Reviews of Geophysics, Volume 57, Issue 4, Page 1289-1337, December 2019., 2019 Abstract Paleomagnetic records from sediments, archeological artifacts, and lava flows provide the foundation for studying geomagnetic field changes over 0–100 ka. Late Quaternary time‐varying spherical harmonic models for 0–100 ka produce a global view used to evaluate new data records, study the paleomagnetic secular variation on centennial to ...

Bulk magnetic domain stability controls paleointensity fidelity [PDF]
, 2017 Nonideal, nonsingle-domain magnetic grains are ubiquitous in rocks; however, they can have a detrimental impact on the fidelity of paleomagnetic records—in particular the determination of ancient magnetic field strength (paleointensity), a key means of ...
