They generally consist of molecular rings (triangles, squares, hexagons) of lanthanide(III) ions, particularly of dysprosium, but there are recent examples of non-ring systems. The pioneering work by Powell, Chibotaru, et al. on µ3-OH bridged Dy3 triangles revealed the requisite molecular geometry, the directions of the magnetic moments on each Dy, the nature of magnetisation vs. field plots (often S-shaped) and relevant theory.1 From a more applied perspective, SMTs offer possible uses in quantum information processing, high-density data storage and as nanoscale devices such as molecular spin valves and spin transistors. III III III A novel class of “double triangles” of type [Dy 6M (OH)8(o-tol)12(MeOH)5(NO3)]·4MeOH, where M = 2 III Cr, Mn, Fe, Co, Al, o-tol = o-toluate, in which the M ion bridges the two Dy3 triangles in a MO6 coordination environment (see Fig.). The parent CrIII system2a showed a rare ferrotoroidal arrangement of the toroidal moments on each triangle. Comparisons will be made2b to the new MIII-bridged materials which include paramagnetic MnIII and FeIII and diamagnetic CoIII and p-block AlIII. New theory has allowed simulation of their microSquid hysteresis loops. 1. (a) J. Tang, I. Hewitt, N. T. Madhu, G. Chastanet, W. Wernsdorfer, C. E. Anson, C. Benelli, R. Sessoli, A. K. Powell, Angew.

Here I discuss our NV-based magnetic imaging experiments as applied to condensed matter systems, where we have imaged current flow patterns in graphene as well as skyrmions, nanoscale spin textures. A grand challenge to improving the spatial resolution and magnetic sensitivity of the NV is mitigating surface-induced quantum decoherence, which I will discuss in the second part of this talk. Decoherence at interfaces is a universal problem that affects many quantum technologies, but the microscopic origins are as yet unclear. Our studies guide the ongoing development of quantum control and materials control, pushing towards the ultimate goal of NV-based single nuclear spin imaging. 6 Prof. Daniella Goldfarb: Plenary Lecture Characteristics of Gd(III) spin labels for the study of protein conformations Daniella Goldfarb Weizmann Institute of Science, Rehovot, Israel Abstract Gd(III) complexes are currently established as spin labels for structural studies of proteins using pulse dipolar electron paramagnetic resonance (PD-EPR) techniques. This has been achieved by the availability of medium- and high-field spectrometers,
