A Frustrated Antipolar Phase Analogous to Classical Spin Liquids. [PDF]

Adv Mater
EuAl12O19 crystals realize an electric analogue to one of the famous models of frustrated magnetism: the Ising triangular lattice antiferromagnet. Electric dipoles on a triangular lattice preferentially align antiparallel to their neighbors yet fail to form any long‐range order, even at the lowest temperatures.

Leveraging 3d-4f Coordination: Molecular Quantum Spring-Magnet Behavior in Axial Ni₂Ln Complexes. [PDF]

Angew Chem Int Ed Engl
We report heterotrimetallic Ni2Ln complexes mimicking exchange spring magnets at the molecular level. CASSCF calculations show collinear anisotropy axes, while µSQUID studies reveal slow relaxation and open hysteresis in Ni2Tb, Ni2Dy, and Ni2Ho. Ferromagnetic 3d–4f coupling and anisotropy alignment enhance bistability, offering promise for quantum, and
