Study of the magnetic chirality in beta-CaCr2O4
beta-CaCr2O4 is a zigzag chain compound for which an incommensurate magnetic order sets in below 21K. The magnetic structure consists in a cycloidal arrangement with the spins confined in the (a,c) plane and the propagation vector is k=(0 0 0.47). A powder study shows that the magnetic ordering sets in following two steps which consist in the onset of a collinear spin-density wave parallel to the a-axis followed by the onset of a secondary component along c allowing the cycloidal modulation of the moments. Furthermore, a non-uniform chirality of the cycloids along the triangular chains was reported. We would like to confirm these results in a single crystal study using spherical polarimetry. We hence request 5 days on D3 with the CRYOPAD option.
