Fig. 2: Ba4Ir3O10: structural properties of the field-altered (in red) and non-altered (in blue) single crystals.
From: Quest for quantum states via field-altering technology

The temperature dependence of the lattice parameters (a) the a and c axis, (b) the b axis and (c) the unit cell volume V. (d) and (e) the crystal structure in the ab and bc plane, respectively. (f) The Ir-Ir bond distance within a trimer. (g) The Ir-O-Ir bond angle between corner-sharing trimers (the marked values are for 100K).
