Abstract
The magnetic ordering in PrB6 has been studied by neutron diffraction on single crystal. PrB6 orders at TN=6.9 K in an incommensurate double-k structure. At TIC= 3.9 K a lock-in transition leads to a commensurate double-k ordering. These results are discussed on the basis of quadrupolar and magnetic interactions. The behaviour of PrB6 is compared with that of CeB6 and NdB6.
