Uncovering correlated paramagnetism in mixed-metal 2D thiocyanates
Two-dimensional magnets offer a platform for exploring both fundamental questions in condensed matter physics and a potential route to new information technology integrating magnetic and electronic functionality. Recently, it has become clear that mixed-metal magnets can have properties distinct from either end member, suggesting that these materials could possess novel physics in their own right. In this proposal we will investigate the transition between Co(NCS)2, a stripe antiferromagnet, and Ni(NCS)2, which has ferromagnetic interactions within the layer but orders antiferromagnetically, by studying mixed-metal compounds (Co,Ni)(NCS)2. Our bulk characterisation indicates that although they appear homogenous, there are significant non-linearities in their magnetic behaviour, indicative of short-range magnetic correlations. The unique capabilities of D7 will allow us to measure diffuse scattering signatures of both structural and magnetic correlations, and inderstanding how these correlations emerge will not only allow us to understand the behaviour of this interesting class of materials but shed light on the interaction between disorder and magnetism in layered magnets.
