Bending the Sierra Madre Oriental: A Paleocene Orocline

Tectonics, Volume 44, Issue 11, November 2025.
Abstract The Sierra Madre Oriental belt of the Mexican thin‐skinned fold‐and‐thrust belt, which formed during the Late Cretaceous due to the subduction of the Farallon Plate beneath North America, exhibits a pronounced curvature of approximately 100°, concave to the southwest.

Rotational remagnetization and orientational transitions in submicron YIG films

EPJ Web of Conferences, 2018
It is shown that for the quasinormal remagnetization of the submicron YIG films with the normal along the [111] axis, which are in the single-domain state, two types of orientation transitions (OT) due to the influence of easy axes can be distinguished ...

New Permian Paleomagnetic and Geochronologic Results From the Alxa Block: Constraints on Its Tectonic Affinity and the Closure of Paleo‐Asian Ocean

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract The Paleo‐Asian Ocean's (PAO) closure timing and the Alxa Block's (ALB) tectonic affinity remain debated. We present new paleomagnetic and geochronologic data from Permian volcanic and sedimentary rocks in the ALB. Characteristic remanent magnetization (ChRM) directions from Early (∼282 Ma), Middle (∼268 Ma), and Late Permian (∼255 Ma) rocks ...

Micromagnetic Simulations of Chemical Remanent Magnetization Acquisition in Single‐Vortex Magnetite Particles

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Magnetic minerals can preserve remanent magnetization to provide ancient magnetic field records. Although thermoremanent magnetization (TRM) is well understood, chemical remanent magnetization (CRM) from chemical processes is also prevalent in nature and can complicate TRM records by introducing additional remanence signals.

Contrasting Recording Efficiency of Chemical Versus Depositional Remanent Magnetization in Sediments

Geophysical Research Letters
How and when sedimentary rocks record Earth's magnetic field is complex. Most studies assume a time‐progressive lock‐in mechanism during sediment deposition called depositional remanent magnetization (DRM).

Coherent Magnetization Rotation of a Layered System Observed by Polarized Neutron Scattering under Grazing Incidence Geometry

Crystals, 2019
The in-plane magnetic structure of a layered system composed of polycrystalline grains smaller than the ferromagnetic exchange length was studied to elucidate the mechanism controlling the magnetic properties considerably different from the bulk using ...

Quasi-Superradiant Soliton State of Matter in Quantum Metamaterials [PDF]

, 2016
Strong interaction of a system of quantum emitters (e.g., two-level atoms) with electromagnetic field induces specific correlations in the system accompanied by a drastic insrease of emitted radiation (superradiation or superfluorescence).

First Paleomagnetic Results From Late Triassic Volcanic Rocks of the Yidun Terrane, Eastern Tibetan Plateau: Constraints on the Closure of the Paleo‐Tethys Ocean

Geophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract To constrain the temporal and spatial evolution of the Ganzi‐Litang Paleo‐Tethys Ocean, this study presents the first paleomagnetic results from Late Triassic volcanic rocks in the Yidun terrane in the eastern Tibetan Plateau. The mean paleomagnetic direction for 27 sites is Ds = 39.2°, Is = −52.9°, κs = 42.2, α95 = 4.3°, and the paleomagnetic
