Varying A-site radius and size disorder to tune magnetic ordering in compositionally complex perovskite oxides
Madeleine Geers, Ravi Kiran Dokala, Roland Mathieu +1
A long standing goal of magnetochemists is to be able to control ordering temperatures through compositional engineering. Here we report the synthesis of a perovskite oxide with tw…
Tuning structural modulation and magnetic properties in metal-organic coordination polymers [CHNH]CoNi(HCOO)
Madeleine Geers, Oscar Fabelo, Matthew J. Cliffe +1
Three solid solutions of [CHNH]CoNi(HCOO), with = 0.25 (1), 0.50 (2) and 0.75 (3), were synthesized and their nuclear structures and magnetic properties…
Magnetic structure and properties of the honeycomb antiferromagnet [Na(OH)]Mn(NCS)
Madeleine Geers, Thomas B. Gill, Andrew D. Burnett +4
We report the magnetic structure and properties of a thiocyanate-based honeycomb magnet [Na(OH)]Mn(NCS) which crystallises in the unusual low-symmetry trigonal space gr…
High pressure behaviour of the magnetic van der Waals molecular framework Ni(NCS)
Madeleine Geers, David M. Jarvis, Cheng Liu +12
Two-dimensional materials offer a unique range of magnetic, electronic and mechanical properties which can be controlled by external stimuli. Pressure is a particularly important s…
Non-collinear magnetism in the post-perovskite thiocyanate frameworks CsM(NCS)
Madeleine Geers, Jie Yie Lee, Sanliang Ling +3
AMX compounds are structurally diverse, a notable example being the post-perovskite structure which adopts a two-dimensional framework with corner- and edge-sharing octahedra.…
