Open Magnetic Fields in the Martian Magnetosphere Revealing Dipole-like Intrinsic Magnetic Fields at Mars

open access: yesThe Astrophysical Journal Letters, 2023
Mars’s magnetosphere is hybrid, having contributions from both an induced magnetosphere like Venus and the localized crustal magnetic fields. However, the planetary fields also include large-scale, more global components.

Feasibility of Parylene Coating for Planar Electroporation Copper Electrodes

open access: yesMedžiagotyra, 2017
This paper is focused on the feasibility study of parylene as a biocompatible coating for planar electroporation microelectrodes. The planar parallel and the circular interdigitated electrodes are applied in the analysis.

The magnetic properties of the hollow cylindrical ideal remanence magnet [PDF]

open access: yesJournal of Magnetism and Magnetic Materials, Vol. 416, 321-324,, 2016, 2016
We consider the magnetic properties of the hollow cylindrical ideal remanence magnet. This magnet is the cylindrical permanent magnet that generates a uniform field in the cylinder bore, using the least amount of magnetic energy to do so. The remanence distribution of this magnet is derived and the generated field is compared to that of a Halbach ...

Quark condensate and magnetic moment in a strong magnetic field [PDF]

open access: yes, 2022
This paper studies the quark condensate, magnetic moment, magnetic polarization, and magnetic susceptibility in a strong external magnetic field by employing the Dyson-Schwinger equations (DSE). The results show that these physical quantities as functions of the magnetic field.

Consistent generation of magnetic fields in axion inflation models [PDF]

open access: yes, 2015
There has been a growing evidence for the existence of magnetic fields in the extra-galactic regions, while the attempt to associate their origin with the inflationary epoch alone has been found extremely challenging.

Magnetic fields and UHECR propagation [PDF]

open access: yesEPJ Web of Conferences, 2023
I review the main observational tools used to detect and measure magnetic fields in the interstellar medium of our Galaxy (considering both the Galactic disk and the Galactic halo), in the interstellar medium of external galaxies, and in the ...

Evolution of Rotating Molecular Cloud Core with Oblique Magnetic Field [PDF]

open access: yesAstrophys.J. 645 (2006) 1227-1245, 2006
We studied the collapse of rotating molecular cloud cores with inclined magnetic fields, based on three-dimensional numerical simulations.The numerical simulations start from a rotating Bonnor-Ebert isothermal cloud in a uniform magnetic field. The magnetic field is initially taken to be inclined from the rotation axis.
