摘要： A material for a magnetic resonance installation is provided, wherein the material includes a support material and a magnetic doping material which is admixed in a specific proportion. The doping material exhibits an anisotropic susceptibility. In respect of the anisotropic susceptibility, the doping material exhibits a mean orientation along a predefined direction. An essentially homogeneous intermixture of the support material and the doping material is present within a volume of the material which is smaller than 1 mm3.
