Magnetic structure and spin density determination at the new organic Honeycomb biradical F4BIPBNN
We have succeeded in synthesizing a new organic biradical F4BIPBNN which forms an S = 1/2 Heisenberg 3D honeycomb antiferromagnet. Alternate stacking of honeycomb layers with 4 exchange pathways is realized. Antiferromagnetic long range order has been observed below TN = 2.7 K at zero magnetic field. Static magnetic susceptibility including TN and magnetization curves are well reproduced by quantum Monte Carlo calculations with three antiferromagnetic interactions of 4.2-6.6 K. The goal of the present experimental proposal is double. On one side our research group is interested in the exploration of the magnetic phase diagram of F4BIPBNN by the determination the magnetic structure of below 0.4K. This will help to understand the different magnetic interactions schemes proposed by the magnetometry and MO calculations. On the other hand, the collected data at D9 will be used to determine with high accuracy the nuclear structure factors at low temperature as a previous step to proceed with the spin density determination, for which we apply to beamtime also at D3 instrument
