Determination of the magnetic anisotropy axes of a new Cr10 wheel compound
Our research group has successfully synthesized single crystals of a new member of the wheel family of Cr10 compounds based on methoxy and formate (HCOO-) anions. Magnetization shows that XT at room temperature is consistent for ten uncoupled paramagnetic centers with S = 3/2 (19 emu K mol-1). When the temperature decreases, the XT product slightly increases until 50 K, when the increase is more abrupt, reaching a maximum at 18 K, then dropping suddenly. To understand this complex magnetic data, we performed DFT calculations of J. These results led to a model of two sets of ferromagnetic chromium cations connected by two cations in an asymmetric antiferromagnetic coupling, achieving a ground state of S = 9. To complete this study, we are currently working on magnetic anisotropy calculations that would be perfectly complemented with polarized neutron diffraction to understand the role of this property in the magnetic model we are proposing
