Most notably, some novel chiral auxiliary ligands such as ferrocene- or biaryl backbone-containing monophosphine, bisphosphines, bis …
WebAug 9, 2024 · In this work, we report enantiomeric organic chiral ferrimagnets, where the chirality results from the molecular torsion by propeller-like arrangement of the donor and acceptor molecules. The ferrimagnetism results from the difference in electron–phonon coupling of the donor and acceptor inside the chiral crystals. WebMar 29, 2024 · This coupling is mediated by chiral domain walls between out-of-plane and in-plane magnetic regions and dominates the behavior of nanomagnets below a critical size. We used this concept to realize lateral exchange bias, field-free current-induced switching between multistate magnetic configurations as well as synthetic antiferromagnets ...
