Seebeck effect in nanomagnets [PDF]
Journal of Physics: Condensed Matter, 2021 Abstract We present a theory of the Seebeck effect in nanomagnets with dimensions smaller than the spin diffusion length, showing that the spin accumulation generated by a temperature gradient strongly affects the thermopower. We also identify a correction arising from the transverse temperature gradient induced by the anomalous ...

Crossing and Anticrossing of Exchange-Coupled Molecular Spin Excitation Energy Levels. [PDF]
SmallOrientation matters: The excitation energy levels of exchange‐coupled spins of two nickelocene molecules anchored to superconducting electrodes are explored via inelastic electron tunneling spectroscopy. Depending on the tilt angle of the single‐molecule magnetic probe the levels cross or exhibit avoided crossing. Abstract The superconducting Pb tip of

Single-Molecule Nanomagnets [PDF]
Annual Review of Condensed Matter Physics, 2010 Single-molecule magnets straddle the classical and quantum mechanical worlds, displaying many fascinating phenomena. They may have important technological applications in information storage and quantum computation. We review the physical properties of two prototypical molecular nanomagnets, Mn12-acetate and Fe8: Each behaves as a rigid, spin-10 ...
