Long-range ferromagnetic dipolar ordering of high-spin molecular clusters
A. Morello, F. L. Mettes, F. Luis +5
We report the first example of a transition to long-range magnetic order in a purely dipolarly interacting molecular magnet. For the magnetic cluster compound Mn6O4Br4(Et2dbm)6, th…
The Instantonic Approach with Non-Equivalent Vacua
J. Casahorran
We study the quantum-mechanical tunneling phenomenon in models which include the existence of non-equivalent vacua. For such a purpose we evaluate the euclidean propagator between…
Effective Strong Dimension, Algorithmic Information, and Computational Complexity
Krishna B. Athreya, John M. Hitchcock, Jack H. Lutz +1
The two most important notions of fractal dimension are {\it Hausdorff dimension}, developed by Hausdorff (1919), and {\it packing dimension}, developed by Tricot (1982). Lutz (200…
The Critical State in Type-II Superconductors with Cross-Flow Effects
A. Badia, C. Lopez
A theoretical framework is presented, which allows to explain many experimental facts related to pinning and cross-flow effects between flux tubes in type-II superconductors. It is…
Magnetic properties of alpha-iron(II) phthalocyanine
M. Evangelisti, J. Bartolome, L. J. de Jongh +1
We report on the magnetic properties of the supra-molecular compound iron(II) phthalocyanine in its alpha-form. dc- and ac-susceptometry measurements and Mossbauer experiments show…
Bifurcation Curves of Limit Cycles in some Lienard Systems
Ricardo Lopez-Ruiz, Jose-Luis Lopez
Lienard systems of the form , with f(x) an even continous function, are considered. The bifurcation curves of limit cycles are calculated exactly in the…
