Introduction à la relaxation électronique dans les solides : mécanismes et techniques de mesure

Abstract: Les fluctuations des moments magnétiques électroniques dans les solides peuvent être étudiées par plusieurs techniques, électroniques ou nucléaires. Cet article est une introduction aux mécanismes de relaxation paramagnétique les plus fréquemment rencontrés (phonons, électrons de conduction, interactions d'échange ou dipolaires) dans la matière condensée, et aux différentes techniques de mesure des fréquences de relaxation : résonance paramagnétique électronique, résonance nucléaire, spectroscopie Mössbauer, d… Show more

“…In this review we will be concerned only with the study of relaxation effects by means of Mossbauer spectroscopy. For a more general review which includes the study of relaxation effects by all the different possible techniques, the reader is referred to the papers of Hartmann-Boutron (1975) and Bonville (1983). As is common practice, we use the term 'electronic relaxation' to indicate the study of the transitions between electronic levels.…”
