A {Cr^III₂Dy^III₂} Single‐Molecule Magnet: Enhancing the Blocking Temperature through 3d Magnetic Exchange

Abstract

Butterfly magnet: The replacement of diamagnetic CoIII for CrIII in a 3d-4f butterfly complex results in vastly improved single-molecule magnet properties. Longer relaxation times are found, with magnetic hysteresis observed. This is due to exchange interactions between the DyIII and CrIII ions, resulting in a multilevel exchange barrier with significantly reduced quantum tunneling of the magnetization.
