Dolgovskiy, Vladimir Fescenko, Ilja Sekiguchi, N. Colombo, Simone Lebedev, Victor Zhang, J. Weis, Antoine 2016-07-11 We describe a magnetic source imaging camera (MSIC) allowing a direct dynamic visualization of the two-dimensional spatial distribution of the individual components Bx(x,y), By(x,y) and Bz(x,y) of a magnetic field. The field patterns allow—in principle— a reconstruction of the distribution of sources that produce the field B→ by inverse problem analysis. We compare experimentally recorded point-spread functions, i.e., field patterns produced by point-like magnetic dipoles of different orientations with anticipated field patterns. Currently, the MSIC can resolve fields of ≈10 pT (1 s measurement time) range in a field of view up to ∼20 × 20 mm2. The device has a large range of possible applications. As an example, we demonstrate the MSIC's use for recording the spatially resolved Néel magnetorelaxation of blocked magnetic nanoparticles. application/pdf https://folia.unifr.ch/global/documents/305189 https://folia.unifr.ch/documents/305189/files/wei_msi.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1063/1.4958700 info:eu-repo/semantics/openAccess License undefined Applied Physics Letters. - 2016, vol. 109, no. 2, p. 023505 info:eu-repo/classification/udc/53 A magnetic source imaging camera http://purl.org/coar/resource_type/c_6501
