SINGLE-MOLECULE MAGNETS

Ultrafast control of anisotropy

Single-molecule magnets are able to store information through their magnetic anisotropy, making them very promising systems for memory applications. Now, femtosecond-laser-initiated molecular dynamics that modulate magnetic anisotropy have been observed, paving the way for operation on ultrafast timescales.
