Doping-induced Ferromagnetic order and its unusual evolution to Helical Antiferromagnetic Order in Sr(Ni $_{1 - x}$ Co $_{x}$ ) $_{2}$ P $_{2}$

A. Sapkota, J. Schmidt, J. M. Wilde +6

SrNi $_{2}$ P $_{2}$ represents a unique case of a collapsed structural phase (one-third collapsed, where one out of every three P-P pairs forms a bond) in the A(TM) $_{2}$ X $_{2}$ family of co…

Magnetism and Peierls distortion in Dirac semimetal CaMnBi $_{2}$

Aashish Sapkota, Niraj Aryal, Xiao Hu +9

Dirac semimetals of the form $A$ Mn $X_{2}$ ( $A =$ alkaline-earth or divalent rare earth; $X =$ Bi, Sb) host conducting square-net Dirac-electron layers of $X$ atoms interleaved with a…
