The technique of spin-echo NMR allows the effective magnetic field (hyperfine field) at the nucleus to be determined and it is highly sensitive to changes in the local atomic environment and in particular to the parent atom's nearest neighbours. text/html 2009-07-18T08:12:33+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.smfi.unipr.it/dokuwiki/doku.php?id=andrey.sidorenko:current_research&rev=1247904753&do=diff Ultimate results of current research Magnetic materials * Au/STO/LSMO/STO heterostructures * NMR in MnAs/GaAs * Co/AlO/Alq3/SiO multilayers * NMR in LSMO/Alq3/AlOx/Co spin valves * NMR in CoPt alloy films * NMR in Nanoclusters in bulk DMS's InSb doped with Mn ions * Mn6Cr Other * Oscillations of magnetic moment in LSMO thin films measured by SQUID * Magnetic moment of Pd vs time * Magnetic moment of CoPt vs time * NMR in Iron based superconductors text/html 2014-02-14T09:49:30+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.smfi.unipr.it/dokuwiki/doku.php?id=andrey.sidorenko:cv&rev=1392371370&do=diff Education Ph.D. April 2000 Physics of magnetic and related phenomena, Faculty of Physics, Moscow State University (Russia) Dissertation: The Effects of Crystal Field and Quadrupole Interactions in Rare-Earth Zircons Adviser: Prof. Natalia P.
