Magnetic bistability in a metal-ion cluster
MAGNETIC materials of mesoscopic dimensions (a few to many thousands of atoms) may exhibit novel and useful properties such as giant magnetostriction, magnetoresistivity and magnetocaloric
Quantum tunneling of magnetization and related phenomena in molecular materials.
TLDR
The fundamental concepts needed to understand quantum size effects in molecular magnets are reviewed and critically report what has been done in the field to date are critically reported.
Macroscopic quantum tunnelling of magnetization in a single crystal of nanomagnets
THE precise manner in which quantum-mechanical behaviour at the microscopic level underlies classical behaviour at the macroscopic level remains unclear, despite seventy years of theoretical
High-spin molecules: [Mn12O12(O2CR)16(H2O)4]
The syntheses and electrochemical and magnetochemical properties of [Mn 12 O 12 (O 2 CPh) 16 (H 2 O) 4 ] (3), its solvate 3.PhCOOH-CH 2 Cl 2 , and [Mn 12 O 12 (O 2 CMe) 16 (H 2 O) 4 ].MeCOOH-3H 2 O
Room-Temperature Quantum Coherence and Rabi Oscillations in Vanadyl Phthalocyanine: Toward Multifunctional Molecular Spin Qubits.
TLDR
Rabi oscillations are observed in this nuclear spin-active environment ((1)H and (14)N nuclei) at room temperature also for 2, indicating an outstanding robustness of the quantum coherence in this molecular semiconductor exploitable in spintronic devices.
Quantum Coherence Times Enhancement in Vanadium(IV)-based Potential Molecular Qubits: the Key Role of the Vanadyl Moiety.
TLDR
This investigation, performed by a combined approach of alternate current (ac) susceptibility measurements and continuous wave and pulsed electron paramagnetic resonance (EPR) spectroscopies, revealed that the effectiveness of the vanadyl moiety in enhancing quantum coherence up to room temperature is related to a less effective mechanism of spin-lattice relaxation.
Single-Molecule Magnets
Magnets are widely used in a large number of applications, and their market is larger than that of semiconductors. Information storage is certainly one of the most important uses of magnets, and the
Temperature- and Light-Induced Spin Crossover Observed by X-ray Spectroscopy on Isolated Fe(II) Complexes on Gold.
TLDR
The results clearly demonstrate that temperature- and light-induced spin crossover is possible for isolated molecules on surfaces but that interactions with the surface may play a key role in determining when this can occur.
