The renormalization group for a slab model of the spin reorientation transition
D. Pescia
In 1975, Polyakov invented a renormalization group algorithm for treating the problem of a classical isotropic planar Heisenberg ferromagnet. Here we define a tool - "parallel tran…
Lectures on ultrathin film ferromagnetism
D. Pescia
In these Lecture Notes we review some of the fundamental principles that have emerged from research on the ferromagnetism of ultrathin films consisting of 3d transition-metal overl…
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…
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,…
(Ir-)Reversibility and thermal equilibrium in magnetic domain pattern formation in ultra-thin ferromagnetic films
N. Saratz, U. Ramsperger, A. Vindigni +1
We investigate the details of pattern formation and transitions between different modulated phases in ultra-thin Fe films on Cu(001). At high temperature, the transitions between t…
