متن کاملSlow magnetic relaxation in a cyano-bridged ferromagnetic {Fe(III)Ni(II)} alternating chain.
A cyano-bridged ferromagnetic {Fe(III)Ni(II)} alternating chain {[Fe(pzTp)(CN)3][Ni(chxn)2]}·ClO4·H2O (1) (pzTp = tetrakis(pyrazolyl)borate, chxn = (1R,2R)-1,2-diaminocyclohexane) was synthesized via rational design. Crystal structure analysis and magnetic studies demonstrated that compound had a one-dimensional zigzagging chain-like structure and slow magnetic relaxation.
متن کاملGravity, Rotation and Magnetic Fields
Magnetic fields are fundamental to the dynamics of both accretion disks and the jets that they often drive. We review the basic physics of these phenomena, the past and current efforts to model them numerically with an emphasis on the jetdisk connection, and the observational constraints on the role of magnetic fields in the jets of active galaxies on all scales.
متن کاملFerromagnetic vacuum and galactic magnetic fields
Non-abelian gauge theories may have a ferromagnet-like vacuum with a nonzero magnetic field, which also exists at finite temperature. We argue that the formation of the ferromagnet-like vacuum at GUT scales gives rise to a Maxwell magnetic field imprinted on the comoving plasma, and that it is energetically favourable to align the field in different correlation volumes. This results in a cohere...
متن کاملMagnetic fields and rotation of spiral galaxies
We present a simplified model in which we suggest that two important galactic problems -the magnetic field configuration at large scales and the flat rotation curvemay be simultaneously explained. A highly convective disc produces a high turbulent magnetic diffusion in the vertical direction, stablishing a merging of extragalactic and galactic magnetic fields. The outer disc may then adquire a ...
