From: Orthogonal antiferromagnetism to canted ferromagnetism in CaCo3Ti4O12 quadruple perovskite driven by underlying kagome lattices

Fig. 2

Refined magnetic structures of CaCo3Ti4O12 at 1.6 K and under a 0 T and b 8 T. Red, blue, and green centres each correspond to a set of CoO4 square planes sharing a common orientation. c J1 exchange between 1NN. d Relative arrangement of 1NN centres in the 0 T magnetic structure of CaCo3Ti4O12. e J2 exchange between 2NN. f Relative arrangement of 2NN centres. g J3 exchange between 3NN. h Relative arrangement of 3NN centres. i J4 exchange between 4NN. j Relative arrangement of 4NN centres. k Three different J4 interactions. l Moment directions considered during DFT calculations (detailed in the Supplementary Fig. 4). m Arrangement of the kagome layers along the [111] direction. n A kagome layer of J2 spins perpendicular to [111]. o Projection view of two adjacent kagome layers of J2 spins perpendicular to [111].
