The spatial resolution of magnetic resonance imaging can be greatly enhanced by replacing the coil antenna (or cavity) with a scanning force microscope. We describe how this mechanical detection can be applied to the measurement of both the transverse and longitudinal relaxation inside a micron-size volume. The measurement procedure and analysis is detailed for the case of paramagnetic and ferromagnetic spin systems. To cite this article: O. Klein, V.V. Naletov, C. R. Physique 5 (2004).


La résolution spatiale d'un imageur à résonance magnétique peut être fortement améliorée en remplaçant l'antenne à bobine (ou cavité) par un microscope à force atomique. Nous décrivons comment cette détection mécanique peut être appliquée à l'étude de la relaxation transversale et longitudinale dans des échantillons microscopiques. Le protocole de mesure et d'analyse est décrit pour des spins paramagnétiques et ferromagnétiques. Pour citer cet article : O. Klein, V.V. Naletov, C. R. Physique 5 (2004).
