Multiferroics have been highly topical in the past decade due to potential applications in, amongst others, data storage. Cr2O3 was the first linear magnetoelectric compound, known well before the interest in such materials was revived about ten years ago. However, some aspects of this prototype materials are still poorly understood. The aim of the experiment is to study the spin-flop magnetic structure in Cr2O3 above 6T below 90K in order to propose a model for the magnetic arrangement and magnetic symmetry. The high-field phase displays a torroidal moment due to the spin-reorientation of the antiferromagnetic structure,and hence an off-diagonal agnetoelectric effect. This has never been studied by neutron diffraction. We recently have obtained high-quality single crystals of Cr2O3 and are proposing to study this magnetic state in the dedicated 14T WISH magnet
