Structural ground states of ($A,A^{\prime }$)Cr${}_2$O${}_4$($A$=Mg, Zn; $A^{\prime }$ = Co, Cu) spinel solid solutions: Spin-Jahn-Teller and Jahn-Teller effects

Moureen C. Kemei, Stephanie L. Moffitt, Lucy E. Darago +5

We examine the effect of small amounts of magnetic substituents in the $A$ sites of the frustrated spinels MgCr${}_2$O${}_4$ and ZnCr${}_2$O${}_4$. Specifically we look for the effects of…
