WebThe general conditions for the occurrence of a coincidence site lattice, i.e., for partial coincidence of lattice points in two identical crystal lattices, are derived and a method is outlined for determining the degree of coincidence. The question of atomic coincidence in two actual crystals is discussed, leading to the concept of mixed ... WebThe 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.
