Excess Spin and the Dynamics of Antiferromagnetic Ferritin
J. G. E. Harris, J. E. Grimaldi, D. D. Awschalom +2
Temperature-dependent magnetization measurements on a series of synthetic ferritin proteins containing from 100 to 3000 Fe(III) ions are used to determine the uncompensated moment…

Macroscopic Quantum Coherence in Molecular Magnets
Alain Chiolero, Daniel Loss
We study macroscopic quantum coherence in antiferromagnetic molecular magnets in the presence of magnetic fields. Such fields generate artificial tunnel barriers with externally tu…

Macroscopic Quantum Coherence in Ferrimagnets
Alain Chiolero, Daniel Loss
We study macroscopic quantum coherence (MQC) in small ferrimagnets. Through semi-classical calculations we show that even a small uncompensated moment has a drastic effect on MQC.…
