Advancements in mononuclear dysprosium-based single-molecule magnets via synthetic and molecular engineering

Advancements towards improving the magnetic properties of mononuclear dysprosium-based single-molecule magnets, or as they are more commonly referred to as single-ion magnets, have been reaching their theoretical limits with slow magnetic relaxation in these molecules surpassing the liquid nitrogen barrier in recent years. The targeted design of axial crystal fields for the oblate Kramers ion of dysprosium(III) is responsible for these improvements with the strategies for these crystal fields discussed herein.
