Orbital-spin order and the origin of structural distortion in MgTi${}_2$O${}_4$

S. Leoni, A. N. Yaresko, N. Perkins +2

We analyze electronic, magnetic, and structural properties of the spinel compound MgTi${}_2$O${}_4$ using the local density approximation+U method. We show how MgTi${}_2$O${}_4$ undergoes…
