A single-crystal neutron diffraction study on magnetic structure of CsCo 2 Se 2

The magnetic structure of CsCo2Se2 was investigated using single-crystal neutron diffraction technique.An antiferromagnetic transition with the propagation vector (0,0,1) was observed at TN = 78 K.The Co magnetic moment 0.772(6) µB at 10 K pointing in the basal plane couples ferromagnetically in the plane which stacks antiferromagnetically along the c direction.Tuning and suppressing the interplane antiferromagnetic interaction may be crucial to induce a superconducting state in the material.
