Quantum-enhanced Landauer erasure and storage
Rocco Gaudenzi, Enrique Burzurí, Satoru Maegawa +2
The erasure of a bit of information encoded in a physical system is an irreversible operation bound to dissipate an amount of energy . As a result, work $W \…
Magnetic dipolar ordering and quantum phase transition in Fe8 molecular magnet
E. Burzurí, F. Luis, O. Montero +5
We show that a crystal of mesoscopic Fe8 single molecule magnets is an experimental realization of the Quantum Ising Phase Transition (QIPT) model in a transverse field, with dipol…
Magnetic quantum tunnelling in Fe8 with excited nuclei
Oren Shafir, Amit Keren, Satoru Maegawa +2
We investigate the effect of dynamic nuclear spin fluctuation on quantum tunneling of the magnetization (QTM) in the molecular magnet Fe8 by increasing the nuclei temperature using…
Demonstrating Multi-bit Magnetic Memory in the Fe8 High Spin Molecule by Muon Spin Rotation
Oren Shafir, Amit Keren, Satoru Maegawa +3
We developed a method to detect the quantum nature of high spin molecules using muon spin rotation, and a three-step field cycle ending always with the same field. We use this meth…
Proton Spin Relaxation Induced by Quantum Tunneling in Fe8 Molecular Nanomagnet
Miki Ueda, Satoru Maegawa, Susumu Kitagawa
The spin-lattice relaxation rate and NMR spectra of H in single crystal molecular magnets of Fe8 have been measured down to 15 mK. The relaxation rate s…
Magnetic ordering and fluctuation in kagome lattice antiferromagnets, Fe and Cr jarosites
M. Nishiyama, T. Morimoto, S. Maegawa +2
Jarosite family compounds, KFe_3(OH)_6(SO_4)_2, (abbreviate Fe jarosite), and KCr_3(OH)_6(SO_4)_2, (Cr jarosite), are typical examples of the Heisenberg antiferromagnet on the kago…
