Webb3 apr. 2014 · Bloch-point velocity as a function of the applied field in a wire with a diameter of 60 nm. Different propagation behaviors are found, depending on the relative orientation of the cylinder axis and the atomic lattice. The last data point with zero velocity represents the depinning field. WebbThe introduction of atom 1 into a crystal of atom 2 creates a pinning point for multiple reasons. An alloying atom is by nature a point defect, thus it must create a stress field when placed into a foreign crystallographic position, which could block the passage of … synchrony 2% credit card

WebbWe investigated the possibility of tuning the local switching properties of memristive crystalline SrTiO 3 thin films by inserting nanoscale defect nucleation centers. For that purpose, we employed chemically-synthesized Au nanoparticles deposited on 0.5 wt%-Nb-doped SrTiO 3 single crystal substrates as a defect formation template for the … WebbThe recent discovery of magnetic skyrmion lattices initiated a surge of interest in the scientific community. Several novel phenomena have been shown to emerge from the interaction of conducting electrons with the skyrmion lattice, such as a topological Hall-effect and a spin-transfer torque at ultra-low current densities. WebbWe study the pinning quantum phase transition in a Tonks-Girardeau gas, both in equilibrium and out-of-equilibrium, using the ground state fidelity and the Loschmidt echo as diagnostic tools. The ground state fidelity … thailand liquor hours
