HTS Dipole Magnet with a Mechanical Energy Transfer in the Magnetic Field [PDF]

, 2022
There were designed and successfully tested at Fermilab several high temperature superconducting (HTS) model magnets for particle accelerators. Some of them worked in a persistent current mode continuously generating magnetic field in the iron dominated magnet gap.

Temperature-dependent magnetization in diluted magnetic semiconductors [PDF]

, 2002
We calculate magnetization in magnetically doped semiconductors assuming a local exchange model of carrier-mediated ferromagnetic mechanism and using a number of complementary theoretical approaches. In general, we find that the results of our mean-field

Magnetized Water Irrigation Alleviates Emitter Clogging of a Drip Fertigation System

Agronomy, 2022
Drip fertigation systems are a new technology to alleviate water shortages and improve fertilizer use efficiency. Emitter clogging is the main obstacle to their application. However, few efficient, safe, and environmentally friendly methods are available

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

Remote 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

Le 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.

Engineered Magnetization Dynamics of Magnonic Nanograting Filters

Magnetochemistry, 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 ...
