On the coexistence of dipolar frustration and criticality in ferromagnets
Sergio A. Cannas, Alessandro Vindigni
In real magnets the tendency towards ferromagnetism, promoted by exchange coupling, is usually frustrated by dipolar interaction. As a result, the uniformly ordered phase is replac…
A combined first-principles and thermodynamic approach to M-Nitronyl Nitroxide (M=Co, Mn) spin helices
Marco Scarrozza, Alessandro Vindigni, Paolo Barone +2
The properties of two molecular-based magnetic helices, composed of 3 metal Co and Mn ions bridged by Nitronyl Nitroxide radicals, are investigated by density functional calcula…
Domain-wall free energy in Heisenberg ferromagnets
Boris Sangiorgio, Thomas C. T. Michaels, Danilo Pescia +1
We consider Gaussian fluctuations about domain walls embedded in one- or two-dimensional spin lattices. Analytic expressions for the free energy of one domain wall are obtained. Fr…
Scale invariance of a diodelike tunnel junction
H. Cabrera, D. A. Zanin, L. G. De Pietro +9
We measure the current vs voltage (I-V) characteristics of a diodelike tunnel junction consisting of a sharp metallic tip placed at a variable distance d from a planar collector an…
Single-Chain Magnets
Dante Gatteschi, Alessandro Vindigni
Single-chain magnets are molecular spin chains displaying slow relaxation of the magnetisation on a macroscopic time scale. To this similarity with single-molecule magnets they own…
Static and dynamic properties of Single-Chain Magnets with sharp and broad domain walls
Orlando V. Billoni, Vivien Pianet, Danilo Pescia +1
We discuss time-quantified Monte-Carlo simulations on classical spin chains with uniaxial anisotropy in relation to static calculations. Depending on the thickness of domain walls,…
