Meyer, C., Hartmann-Boutron, F., Greneche, J., Varret, F.

The dramatic effect of an external magnetic field on the 57Fe hyperfine field in Au 19 % Fe 2 % Sn above 45 K could arise from the presence of superparamagnetic clusters.

Effets des fluctuations du couplage quadrupolaire sur les spectres môssbauer des ions dans les cristaux (1968)

Hartmann-Boutron, F.

En nous basant sur des modèles simples, nous examinons quelles peuvent être les répercussions, sur les spectres Mössbauer, des fluctuations du couplage quadrupolaire dues, soit à la relaxation...

Interactions de superéchange en présence de dégénérescence orbitale et de couplage spin-orbite (1968)

Hartmann-Boutron, F.

On étudie l'effet de la dégénérescence orbitale sur les interactions de superéchange dans le cas simple de deux ions de configuration d1, placés dans des environnements octaédriques, et...
