Ferromagnetic Nanoclusters in two-dimensional He
He adsorbed on graphite is an almost ideal two dimensional (2D) fermionic system. The 2D solid, where the interaction between the nuclear spins S = 1 2 is due to multiple spin exchange, has been extensively studied as a model system for strongly interacting fermions in 2D. At high densities in the second layer, three body exchange dominates and leads to Heisenberg ferromagnetism. We report on N...
متن کاملQuantum Criticality in Quasi-Two-Dimensional Itinerant Antiferromagnets.
Quasi-two-dimensional itinerant fermions in the antiferromagnetic (AFM) quantum-critical region of their phase diagram, such as in the Fe-based superconductors or in some of the heavy-fermion compounds, exhibit a resistivity varying linearly with temperature and a contribution to specific heat or thermopower proportional to TlnT. It is shown, here, that a generic model of itinerant anti-ferroma...
متن کاملCyclotron Resonance of Itinerant Holes in Ferromagnetic InMnAs/GaSb Heterostructures
We report the first observation of hole cyclotron resonance (CR) in ferromagnetic InMnAs/GaSb heterostructures both in the high-temperature paramagnetic phase and the low-temperature ferromagnetic phase. We clearly resolve two resonances that exhibit strong temperature dependence in position, linewidth, and intensity. We attribute the two resonances to the so-called fundamental CR transitions e...
متن کاملNegative Thermal Expansion of Ultrathin Metal Nanowires: A Computational Study.
Most materials expand upon heating because the coefficient of thermal expansion (CTE), the fundamental property of materials characterizing the mechanical response of the materials to heating, is positive. There have been some reports of materials that exhibit negative thermal expansion (NTE), but most of these have been in complex alloys, where NTE originates from the transverse vibrations of ...
متن کاملOn the simulation of nearly inviscid two-dimensional turbulence
2009 Elsevier Inc. All rights reserved. We here compare two numerical algorithms in a simple test case involving the simulation of two-dimensional freelydecaying turbulence. The first is a standard pseudo-spectral algorithm, as has been widely used in studies of this problem. The second is a less well known hybrid Eulerian–Lagrangian algorithm based on contour dynamics. The comparison verifies ...
