From: Magnetodielectric detection of magnetic quadrupole order in Ba(TiO)Cu4(PO4)4 with Cu4O12 square cupolas

Figure 2

(a) Crystal structure of Ba(TiO)Cu4(PO4)4 viewed along the [110] direction. The grey dotted line represents a unit cell. (b) Square cupola layer viewed along the [001] direction. Two types of Cu4O12 square cupola clusters, A (upward) and B (downward), are shown. Intraplaquette (J1 and J4) and interplaquette (J2, J3, J5, and J6) exchange interactions are denoted by dotted and dashed lines, respectively. (c) Temperature dependence of magnetic susceptibility for the field along the [100] (black square) and [001] (red circle) directions. (d) Magnetization curves at 1.8 K. (e) Temperature dependence of specific heat divided by temperature.
