Congratulations to Eduardo Mendive-Tapia for winning the poster prize at the annual TCM meeting held at Warwick on Thursday 18th June. The poster described his work on theoretical modelling of the caloric properties of manganese anti-perovskite nitrides. Further information about the work can be found in 'Frustrated magnetism and caloric effects in Mn-based antiperovskite nitrides: Ab initio theory' by J. Zemen, E. Mendive-Tapia, Z. Gercsi, R. Banerjee, J. B. Staunton, and K. G. Sandeman, Phys. Rev. B 95, 184438, (2017). https://doi.org/10.1103/PhysRevB.95.184438.
