Title: Influence of cobalt substitution on the magnetism of NiBr 2

Abstract

Co-substituted Ni 1-xCo xBr 2 (0≤x≤1) single crystals were synthesized using vapor transport. As a result, the physical properties of the crystals were characterized by x-ray powder diffraction, magnetization, and specific-heat measurements. Room-temperature x-ray powder diffraction data indicate that a change from the CdCl 2 structure type to the CdI 2 structure type occurs within 0.562 has a commensurate antiferromagnetic phase below T N ≈ 46 K and an incommensurate magnetic ground state below T IC ≈ 20 K. Both magnetic transitions are affected by cobalt substitution, and the incommensurate phase transition is present up to at least x=0.56. Here, the evolution of magnetism has been studied as a function of cobalt content and is summarized in the temperature-composition phase diagram.
