Vega<br/>We present an atomic scale quantum-mechanical theory based on a noncollinear tight-binding formalism for self-consistent calculations of electronic and magnetic structures of d -metallic systems in an external magnetic field. The theory is applied to the description of the magnetic reversal process ...<br/>[Phys. Rev. B 77, 134446] Published Tue Apr 29, 2008 V. M. Uzdin and A.

The analysis of the field expansion of the ac susceptibility and the observation of aging properties make clear that a spin-glass phase appears below T=39K in the presence of magnetic order. ...<br/><img src="http://prb.aps.org/files/SuggestionPRB30x30.jpg" alt="PRB Editors' Suggestion"/><br/> [Phys.
