Abstract

We report an optimized chemical vapor transport method to grow single crystals of (Mn $_{1 - x}$ Ni $_{x}$ ) $_{2}$ P $_{2}$ S $_{6}$ where x = 0, 0.3, 0.5, 0.7 & 1. Single crystals up to 4\,mm\, $\times$ \,3\,mm\, $\times$ \,200\, $μ$ m were obtained by this method. As-grown crystals characterized by means of scanning electron microscopy, and powder x-ray diffraction measurements. The structural characterization shows that all crystals crystallize in monoclinic symmetry with the space group $C 2/ m$ (No. 12). We have further investigated the magnetic properties of this series of single crystals. The magnetic measurements of the all as-grown single crystals show long-range antiferromagnetic order along all crystallographic principal axes. Overall, the Néel temperature TN is non-monotonous, with increasing $N i^{2 +}$ doping the temperature of the antiferromagnetic phase transition first decreases from 80 K for pristine Mn $_{2}$ P $_{2}$ S $_{6}$ (x = 0) up to x = 0.5, and then increases again to 155 K for pure Ni $_{2}$ P $_{2}$ S $_{6}$ (x = 1). The magnetic anisotropy switches from out-of-plane to in-plane as a function of composition in (Mn $_{1 - x}$ Ni $_{x}$ ) $_{2}$ P $_{2}$ S $_{6}$ series. Transport studies under hydrostatic pressure on the parent compound Mn $_{2}$ P $_{2}$ S $_{6}$ evidence an insulator-metal transition at an applied critical pressure of ~22 GPa
