Anomaly crust fields from MAGSAT satellite measurements:their processing and interpretation [PDF]

Annals of Geophysics, 2004
The space distribution of the magnetic anomaly field for the Pacific Ocean is obtained from data of the satellite MAGSAT. A number of long-wavelength magnetic anomalies of the region are identified. A spectrum analysis of a number of profiles of the

Significance of Short‐Wavelength Magnetic Anomaly Low Along the East Pacific Rise Axis, 9°50′N [PDF]

, 2023
Magnetic anomaly variations near mid‐ocean ridge spreading centers are sensitive to a variety of crustal accretionary processes as well as geomagnetic field variations when the crust forms.

Pressure-Tuned Superconducting Dome and Persistent Charge-Density-Wave Order in NdSeTe₂. [PDF]

Adv Sci (Weinh)
NdSeTe2 exhibits an unusual pressure‐tuned phase diagram in which charge‐density‐wave order does not disappear at optimal superconductivity. Instead, Raman spectroscopy reveals a transformation from long‐range to short‐range correlations that remain invisible to resistivity and persist across the entire superconducting dome.

New High-T_c Charge-Transfer Multiferroicity in the Quasi-2D Antiferromagnet CrSbS₃. [PDF]

Adv Sci (Weinh)
ABSTRACT Low‐dimensional magnets, particularly 2D systems, offer a rich platform for realizing unconventional multiferroic mechanisms, especially when multiple polarization channels coexist. In the quasi‐2D antiferromagnet CrSbS3, which crystallizes in the centrosymmetric orthorhombic space group Pnma and orders magnetically at TN ≈ 90 K, two ...

Multiferroic Quantum Criticality in a Proper Ferroelectric Quasi-one-dimensional Ising Antiferromagnet. [PDF]

Adv Sci (Weinh)
Sr1−xBaxCo2V2O8 is established as a magnetic‐ion‐based proper displacive ferroelectric whose transition is continuously suppressed by Ba substitution to a ferroelectric quantum critical point. In the resulting quantum paraelectric regime, a transverse magnetic field induces magnetic quantum criticality, realizing multiferroic quantum criticality and ...

Turbulence driven magnetic reconnection causing long-wavelength magnetic islands [PDF]

, 2010
Magnetic reconnection caused by turbulence in a current sheet is studied by means of numerical simulations of fluid equations. It is found that turbulence produces long-wavelength magnetic islands even if the current sheet is so thick that spontaneous ...

Crustal magnetization and long‐wavelength aeromagnetic anomalies of the Minto block, Quebec [PDF]

Journal of Geophysical Research: Solid Earth, 1999
Measured susceptibilities of >3500 samples from a 500×500 km area of the Minto block, Superior province, Quebec, have an average value of ∼0.03 SI (equivalent to induced magnetizations of ∼1.5 A/m). Charnockitic lithologies (igneous orthopyroxene‐bearing granodiorite, granite, diorite), that constitute large parts of the Minto region, yield the ...
