Testing the Accuracy of Paleointensity Estimates Using Experimental Pottery Assemblages
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract Paleointensity estimates from archaeological pottery represent a key source of information on Holocene variations in geomagnetic field intensity. Yet, pottery rarely exhibits ideal single‐domain behavior that fully satisfies the theoretical assumptions underlying absolute paleointensity methods.

Rotation in the Southeastern Caribbean Arc (Grenadines) Accommodated by Back‐Arc Basin Inversion
Tectonics, Volume 45, Issue 4, April 2026.Abstract The Caribbean tectonic plate is typically modeled as a rigid plate moving along discrete plate boundaries. Isolated exposures on islands have long shown that above the Lesser Antilles subduction zone, the plate experienced contractional, strike‐slip, and extensional deformation, but the importance of this deformation remained long unknown ...

Burn‐Safe Biodegradable Magnetocaloric Composites for Temperature‐Controlled Biomedical Applications
Advanced Science, Volume 13, Issue 15, 13 March 2026.This work investigates a magnetocaloric (Mn,Fe)2(P,Si) compound tailored for precise, self‐regulating heating in biomedical use. With a Curie temperature tuned at 43 °C, it enables therapeutic activation without overheating. Encapsulation in a composite ensures controlled temperature rise under an alternating magnetic field (AMF), with high ...

Measurement of Thermomagnetic Convection Effect in a Cooling Process
, 2019 An experiment is performed to measure the thermomagnetic convection effect in a prototype immersed coil. A magnetic fluid (Midel vegetable oil - CoFe 2 O 4 Cobalt ferrite magnetic fluid) with nanoparticles volume fraction of 5% is used as a coolant for this purpose. The test cell consists of a copper coil, in the form of a two-wire conductor, chosen to

Coercivity and nanostructure of melt-spun Ti-Fe-Co-B-based alloys
AIP Advances, 2016 Nanocrystalline Ti-Fe-Co-B-based alloys, prepared by melt spinning and subsequent annealing, have been characterized structurally and magnetically. X-ray diffraction and thermomagnetic measurements show that the ribbons consist of tetragonal Ti3(Fe,Co ...
