Periodic Reporting for period 1 - ELECTRA (ELEctrically ConTRolled magnetic Anisotropy)
Período documentado: 2022-06-01 hasta 2023-11-30
1) We have shown for the first time that the magnetic anisotropy switch phenomenon could be preserved and observed on molecular layers. This constitutes a cornerstone result in the field of magnetochemistry because it paves the way to use the magnetic anisotropy switches in real spintronic devices. The system constitutes an ideal platform to study SE effects on the surface, however at the moment we are not aware of technique with sufficient sensitivity to do so. We will test the sensitivity newly designed experimental setup and assess if such measurement will be feasible.
2) We have shown that the Dy(ODA) complex exhibits a strong SE effect (the second strongest value ever observed after HoPOM20). Moreover, we have unequivocally assessed the role of chirality in the SE effect: reversing the chirality reverses the SE effect. The result is however not published yet because the ab initio calculations cannot reproduce the experimentally observed magnitude. We plan on refining the calculations including more effects.
3) We have shown that the water molecule is the key ligand to tune the magnetic anisotropy of the LnDOTA complexes. Our experimental investigation proofs that the water removal causes a change of magnetic anisotropy in three derivatives (Ln = Tb, Dy, Ho) from easy axis to easy plane. Also, we have developed an innovative synthetic protocol based on ionic strength and packing effects to remove the water ligand using water as a solvent.
