Oriented 3D Magnetic Biskyrmions in MnNiGa Bulk Crystals. [PDF]

Adv Mater, 2019
Biskyrmion scattering is measured in a single‐crystalline centrosymmetric MnNiGa bulk sample using small‐angle neutron scattering. The biskyrmions are not long‐range ordered, and all of the disordered biskyrmions have their in‐plane symmetry axis aligned along certain directions, governed by the magnetocrystalline anisotropy. Such an anisotropic nature

Cuckoo search with Lévy flights for weighted Bayesian energy functional optimization in global-support curve data fitting. [PDF]

ScientificWorldJournal, 2014
The problem of data fitting is very important in many theoretical and applied fields. In this paper, we consider the problem of optimizing a weighted Bayesian energy functional for data fitting by using global‐support approximating curves. By global‐support curves we mean curves expressed as a linear combination of basis functions whose support is the ...
