How to cross an energy barrier at zero Kelvin without tunneling effect
Seiji Miyashita, Bernard Barbara
This paper deals with the broad class of magnetic systems having a single or collective spin with an energy barrier, such as Rare-Earth elements and their compounds, Single Mol…
Soap bubbles on the surface of a liquid: a playful universe in 3+1 dimensions, a real universe in 4+1 dimensions
H. Bartholin, B. Barbara
Very simple experiments based on an analogy between two theories (gravitation and capillarity) allowed us to construct a two dimension space toy-universe composed of the surface of…
Distribution of eigenstate populations and dissipative beating dynamics in uniaxial single-spin magnets
Takuya Hatomura, Bernard Barbara, Seiji Miyashita
Numerical simulations of magnetization reversal of a quantum uniaxial magnet under a swept magnetic field [Hatomura, \textit{et al}., \textit{Quantum Stoner-Wohlfarth Model}, Phys.…
Coherent spin dynamics in gadolinium-doped CaWO4 crystal
E. I. Baibekov, M. R. Gafurov, D. G. Zverev +4
We report the first observation of Rabi oscillations in the spin-7/2 ensemble of trivalent gadolinium ions hosted in CaWO single crystal. A number of transitions within the low…
Quantum Stoner-Wohlfarth model
Takuya Hatomura, Bernard Barbara, Seiji Miyashita
The quantum mechanical counterpart of the famous Stoner-Wohlfarth model -- an easy-axis magnet in a tilted magnetic field -- is studied theoretically and through simulations, as a…
Anisotropy of the molecular magnet V spin Hamiltonian detected by high-field electron spin resonance
M. Martens, J. van Tol, N. S. Dalal +7
The molecular compound K[VAsO(HO)] 8HO, in short V, has shown important quantum effects such as coherent spin oscillations.…
