Evidence for Jahn-Teller distortions at the antiferromagnetic transition in LaTiO${}_3$

J. Hemberger, H. -A. Krug von Nidda, V. Fritsch +8

LaTiO${}_3$ is known as Mott-insulator which orders antiferromagnetically at $T_{\mathrm{N}}=146$ K. We report on results of thermal expansion and temperature dependent x-ray diffraction…
