The understanding of the magnetisation evolution upon femtosecond optical pumping remains elusive. The authors perform resonant X-ray magnetic scattering measurements and multiscale simulations that reveal rapid magnetic order recovery in ferrimagnet

We investigated, using molecular dynamics, how pressure affects the melting point of the recently theorised and epitaxially grown structure NdFe12. We modified Morse potentials using experimental constants and a genetic algorithm code, before running

We investigated the effect of nitrogenation on $3 \times 3 \times 2$ supercell structures of NdFe12- x Ti x from $x = 0.028$ to $x = 1.56$ (~0.2Ti at. % to ~12Ti at. %). We used the molecular dynamics and Boltzmann probabilities to permeate titanium

We investigated the atomic fill site probability distributions across supercell structures of RT12-xTi (R=Nd, Sm, T=Fe, Co). We use a combined molecular dynamics and Boltzmann distribution approach to extrapolate the probability distributions for Ti

We present an adaptive algorithm for the optimal phase space sampling in Monte Carlo simulations of 3D Heisenberg spin systems. Based on a golden rule of the Metropolis algorithm which states that an acceptance rate of [Formula: see text] is ideal to

A systematic investigation on magnetism and spin-resolved electronic properties in double perovskite Ca2CoMoO6 compound was performed by using the full-potential augmented plane wave plus local orbitals (APW[Formula: see text]) method within the gene

A micromagnetic bilayer model, based on the Landau-Lifshitz-Bloch equation, was utilized to study the magnetic, reversal, and spin transport properties of MgO/L10-FePt/Ag/L10-FePt pseudo spin valves. The model simulates a granular bilayer FePt struct
