Magnetic Weyl Semimetals for Spintronic Applications
… modes and derive a Landau-Lifshitz-Gilbert (LLG)-like equation to describe uniform mode dynamics. I also analyze the excitation of dissipative spin waves and the spin superfluidity state in Mn₃X by extending the model to include spatial inhomogeneity. The analytical results are validated …

Microgmagnetics Study of "Seed" Induced Incoherent Magnetic Reversal in a Cobalt Element Array
… stochastic dynamic micromagnetics code using the LLG equation has been developed and applied to study the seed induced magnetic reversal of a cobalt element array. The spin orientation of the seed element is chosen to be antiparallel to the spin orientation of the first element in the array …

Maize dwarf mosaic virus: purification, some physical properties, and yield of virus from several corn hybrids
… of the potato virus Y group. A yield of 9.0-23.0 llg of virus/g fresh weigh.t of field-grown, mechanically inoculated Hy X Cl03 was determined by analytical sucrose density-gradient centrifugation. This represents a yield of purified virus of approximately 25% of that in the clarified sap. Results …

Magnetization Dynamics in Ultrathin Films and Multilayers
… damping tensor in the Landau-Lifshitz- Gilbert (LLG) equation, this study explains the observed unidirectional relaxation in IrMn/CoFe bilayers and co-existence of unidirectional and uniaxial relaxation in MnN/CoFeB bilayers .

Ferromagnetic dynamics in coupled systems
… obeying the linearised Landau-Lifshitz-Gilbert (LLG) equation. From this, the effect of symmetry on the expected resonance spectrum of antiferromagnetically coupled magnetic moments is investigated. Features such as anticrossings and mode degeneracies are shown to be understandable from symmetry …

Study of Magnetization Switching for MRAM Based Memory Technologies
… is studied using the Landau-Lifshitz-Gilbert (LLG) equation of motion. The switching diagram so-called dynamic critical curve of Stonerlike particles subject to short magnetic field pulses is presented, giving useful information for optimizing field pulse parameters in order to make ultrafast …

Current Induced Magnetisation Dynamics in Ferromagnetic Nanowires
… nanowires simplify the Landau-Lifshitz-Gilbert (LLG) equation of magnetisation to arrive at closed-form solutions that limits their applicability (for example operate in the magnetostatic or exchange limits and apply to simple geometries). Numerical models offer more detail but often focus on the …

Micromagnetic Study of Composite Media for High Density Heat Assisted Magnetic Recording
… on the renormalized Landau-Lifshitz-Gilbert (LLG) method. L10 FePt is one promising recording media candidate for HAMR. The transition noise and transition jitter are calculated through magnetic recording simulation accelerated by GPU parallel computing. Thermal fluctuations and Curie …

Numerical approximation of Stratonovich SDEs and SPDEs
… of the stochastic Landau-Lifschitz- Gilbert (LLG) equation in three dimensions. We examine the L2(Ω ) approximation error of the SEI and MSEI schemes numerically and we prove analytically that MSEI achieves a higher order of convergence than SEI. We generalise SEI so that it is suited not only …
