Magnetic and structural phase transition in heavy rare-earth compound DyB 6

Abstract

We report the neutron diffraction experiment on heavy rare-earth hexaboride DyB 6. The results indicate that the structural phase transition occurs at 32 K, and the antiferromagnetic order at T N = 26 K. The propagation vector of the spin structure is found to be k = 〈 1 4 1 4 1 2〉 and triple- k spin structure is proposed.
