Spin Jahn-Teller antiferromagnetism in CoTi${}_2$O${}_5$

Franziska K. K. Kirschner, Roger D. Johnson, Franz Lang +5

We have used neutron powder diffraction to solve the magnetic structure of orthorhombic CoTi${}_2$O${}_5$, showing that the long-range ordered state below 26 K identified in our muon-s…
