Lattice dynamics and magnetic exchange interactions in GeCo2O4, a spinel with S = 1/2 pyrochlore lattice

Prativa Pramanik, Sobhit Singh, Mouli Roy Chowdhury +6

GeCo${}_2$O${}_4$ is a unique system in the family of cobalt spinels ACo${}_2$O${}_4$ (A= Sn, Ti, Ru, Mn, Al, Zn, Fe, etc.) in which magnetic Co ions stabilize on the pyrochlore lattice ex…
