<strong>Breve</strong> <strong>curriculum</strong> <strong>scientifico</strong> <strong>di</strong> <strong>Giuseppe</strong> <strong>Amoretti</strong><br />

Professore or<strong>di</strong>nario del settore <strong>scientifico</strong> <strong>di</strong>sciplinare FIS/01, è stato Direttore del Dipartimento <strong>di</strong><br />

Fisica dell'Univers<strong>it</strong>à <strong>di</strong> Parma da novembre 2001 a <strong>di</strong>cembre 2009. È attualmente rappresentante<br />

dei Professori <strong>di</strong> I Fascia nel Consiglio <strong>di</strong> Amministrazione, ed è stato membro del Senato<br />

Accademico dal 2005 al 2008. Nel 1982-83 ha trascorso un periodo <strong>di</strong> circa due anni presso il DRF<br />

del Centre d'Etudes Nucleaires <strong>di</strong> Grenoble, con una borsa <strong>di</strong> stu<strong>di</strong>o della Comun<strong>it</strong>à Europea<br />

ottenuta dall'Ist<strong>it</strong>uto Europeo degli Elementi Transuranici <strong>di</strong> Karlsruhe. Nel semestre invernale<br />

1991/92 è stato incaricato del corso <strong>di</strong> Magnetismo nei Soli<strong>di</strong> presso l'Univers<strong>it</strong>à <strong>di</strong> Losanna. E'<br />

stato coor<strong>di</strong>natore della rete sulle Interazioni Magnetiche Fondamentali della Sezione D dell'INFM.<br />

E' stato membro del Board of Directors of the European Actinide Research Development Society. E'<br />

autore o coautore <strong>di</strong> circa 150 pubblicazioni su qualificate riviste internazionali riguardanti la fisica<br />

della materia condensata, ed in particolare le proprietà strutturali, elettroniche e magnetiche <strong>di</strong><br />

composti <strong>di</strong> terre rare, attini<strong>di</strong> e metalli <strong>di</strong> transizione. È coautore <strong>di</strong> un recente articolo <strong>di</strong> rassegna<br />

sulle interazioni multipolari in sistemi a elettroni f pubblicato sulla prestigiosa rivista Reviews of<br />

Modern Physics. Negli ultimi anni ha svolto un’intensa attiv<strong>it</strong>à <strong>di</strong> ricerca nel campo del magnetismo<br />

molecolare. I risultati delle sue ricerche sono stati oggetto <strong>di</strong> <strong>di</strong>versi Highlights. Il suo contributo è<br />

principalmente teorico ed è relativo alla progettazione e interpretazione <strong>di</strong> esperimenti che<br />

utilizzano <strong>di</strong>ffusione anelastica <strong>di</strong> neutroni o altre spettroscopie e tecniche <strong>di</strong> bulk (EPR, NMR-<br />

NQR, µSR, Mössbauer, misure magnetiche, calore specifico). Dal 1986 ha proposto ed effettuato<br />

personalmente numerosi esperimenti <strong>di</strong> <strong>di</strong>ffusione <strong>di</strong> neutroni, principalmente presso il Rutherford<br />

Appleton Laboratory (UK) e l'Inst<strong>it</strong>ut Laue Langevin <strong>di</strong> Grenoble. Ha partecipato a numerosi<br />

congressi internazionali e nazionali, anche su inv<strong>it</strong>o, ed ha fatto parte del board <strong>scientifico</strong> e<br />

organizzativo <strong>di</strong> alcuni <strong>di</strong> questi. Ha presieduto e organizzato il Congresso SIF a Parma nel 2003.<br />
