New Evidence Supporting the Pacific Mantle Outflow: Hints from Crustal Magnetization of the Phoenix Plate

open access: yesRemote Sensing, 2022
Magnetic contributions to the Earth’s magnetic field within the lithosphere are known as magnetic anomalies. Magnetic anomaly maps provide insight on magnetic properties of subsurface rock, geological structures, and plate tectonic history.

MAGNETIZATION OF AMORPHOUS MAGNETS

open access: yesLe Journal de Physique Colloques, 1979
The temperature dependence of the distribution of the magnetic moment in an amorphous magnet, where the exchange interactions and the magnitude of the magnetic moment at O K are random variables, has been investigated. In particular, we considered the two-limiting cases, the one with the fixed spin and the other with the fixed interaction.

Transport in the XX chain at zero temperature: Emergence of flat magnetization profiles [PDF]

open access: yes, 1998
We study the connection between magnetization transport and magnetization profiles in zero-temperature XX chains. The time evolution of the transverse magnetization, m(x,t), is calculated using an inhomogeneous initial state that is the ground state at ...

Engineered Magnetization Dynamics of Magnonic Nanograting Filters

open access: yesMagnetochemistry, 2021
Magnonic crystals and gratings could enable tunable spin-wave filters, logic, and frequency multiplier devices. Using micromagnetic models, we investigate the effect of nanowire damping, excitation frequency and geometry on the spin wave modes, spatial ...
