The First Archaeomagnetic Age at Tiwanaku and Implications for Dating Andean Metallurgical Furnaces

Archaeometry, Volume 68, Issue 3, Page 317-329, June 2026.
ABSTRACT This paper presents the first archaeomagnetic dating at Tiwanaku (Andean Altiplano). We compared the geomagnetic field values recorded by a metallurgical furnace against an updated SHAWQ2k‐SH global model and a regional intensity curve, both of which include, for the first time, high‐quality intensity data from the Southern Hemisphere.

La2O3‐Doped ZrO2 Tapes for Enhanced Thermomagnetic Conversion in CoFeB Heterostructures

Journal of the American Ceramic Society, Volume 109, Issue 6, June 2026.
ABSTRACT This work investigates the thermomagnetic response of La2O3‐doped ZrO2/CoFeB heterostructures for energy harvesting applications. La2O3‐doped ZrO2 ceramic tapes were fabricated via tape casting, followed by the deposition of CoFeB ferromagnetic thin films using magnetron sputtering.

Acquisition of Self‐Reversed Magnetization in Greigite Driven by Antiparallel Vortex‐Core Coupling During Low‐Temperature Oxidation

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Self‐reversed magnetization, acquired antiparallel to the external field, can complicate the interpretation of paleomagnetic directional records, particularly in altered greigite‐bearing sediments with anomalous magnetizations. The underlying physical process for this self‐reversal remains poorly constrained.

Analysis of Influence of Nanoparticle Properties on Nanofluid Thermomagnetic Convection Through Modification of System of Forces

Energies
The tendency to design compact systems results in limited space for particular components and heat transfer processes, which influences the removal of heat. Therefore, new methods for heat transfer intensification are being designed. Coupling passive and

Finite Size‐Effects in Martensite Microstructure of Magnetic Shape Memory Films

Small, Volume 22, Issue 19, 1 April 2026.
Magnetic shape memory alloys are a promising multifunctional material system for integration into microsystems. Their multifunctionality arises from the coexistence of ferroelasticity and ferromagnetism. While size‐effects in ferromagnetic microstructure are well understood, corresponding experiments on the ferroelastic microstructure are sparse.

Magnetic Properties of Fe-Nb-B-RE (RE = Tb, Tb/Y, Tb/Nd) Amorphous and Annealed Melt-Spun Ribbons

Crystals
This paper discusses the magnetic properties of Fe-Nb-B-RE (RE = Tb, Tb/Y, Tb/Nd) melt-spun ribbons. Samples were obtained using a typical melt-spinning technique. The dominant amorphous state was confirmed by XRD and thermomagnetic measurements.

Thermomagnetic analysis of nanocrystalline Nd4.5Fe 77B18.5 alloy

, 2009
Changes in the phase composition and crystallite size of a rapid quenched Nd4.5Fe77B18.5 alloy, caused by thermomagnetic measurements (TM) have been studied using XRD methods of phase analysis, crystallite size and lattice microstrain determination. Structural changes in regard to optimal magnetic state were additionally analyzed by TEM.

Late Eocene to Early Oligocene (36–26 Ma) Rock Magnetism and Magnetostratigraphy of IODP Site U1553, Southwestern Pacific: Defying the Challenges of Carbonate Dilution and Reductive Diagenesis

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract The late Eocene to early Oligocene is an intriguing Paleogene period in which the Earth climate state changed from Warmhouse to Coolhouse. Accurate age models are essential for investigating these climate transitions. The southwestern Pacific International Ocean Discovery Program (IODP) Site U1553, with its almost complete succession of the ...
