High Ms Fe16N2 thin film with Ag under layer on GaAs substrate
AIP Advances, 2016 (001) textured Fe16N2 thin film with Ag under layer is successfully grown on GaAs substrate using a facing target sputtering (FTS) system. After post annealing, chemically ordered Fe16N2 phase is formed and detected by X-ray diffraction (XRD).

AIP Advances, 2017 The heating performance of magnetic nanoparticles (MNPs) under an alternating magnetic field (AMF) is dependent on several factors. Optimizing these factors improves the heating efficiency for cancer therapy and meanwhile lowers the MNP treatment dosage.

A three-dimensional spin-diffusion model for micromagnetics [PDF]
Scientific Reports, 2014 We solve a time-dependent three-dimensional spin-diffusion model coupled to the Landau-Lifshitz-Gilbert equation numerically. The presented model is validated by comparison to two established spin-torque models: The model of Slonzewski that describes ...

Dynamics of micromagnetic measurements [PDF]
Physical Review B, 1993 The response of a micromagnetic system to changes in ambient temperature or applied field is studied as a function of the overbarrier relaxation rate and of the intermediate nonequilibrium states through which the system is passing. We first derive an equation for the thermomagnetic curve and the corresponding time-dependent dc susceptibility.

Nonlinear Magnon Scattering Mechanism for Microwave Pumping in Magnetic Films
IEEE Access, 2020 Magnon scattering enables non-linear microwave devices, such as frequency selective limiters and signal to noise enhancers. It may also impact information transfer within spintronic devices.

A Comprehensive Study of Temperature and Its Effects in SOT-MRAM Devices
Micromachines, 2023 We employ a fully three-dimensional model coupling magnetization, charge, spin, and temperature dynamics to study temperature effects in spin-orbit torque (SOT) magnetoresistive random access memory (MRAM).

Interaction Energy of Domain Walls in a Nonlocal Ginzburg–Landau Type Model from Micromagnetics [PDF]
, 2015 We study a variational model from micromagnetics involving a nonlocal Ginzburg–Landau type energy for $${{\mathbb S}^{1}}$$S1-valued vector fields. These vector fields form domain walls, called Néel walls, that correspond to one-dimensional transitions ...

Journal of Applied Physics, 1998 The localization of nucleation modes in inhomogeneous ferromagnets and its influence on the coercivity are investigated. From the formal analogy between quantum mechanics and micromagnetics follows that anisotropy inhomogeneities may cause localization.

Manipulating and trapping skyrmions by magnetic field gradients
New Journal of Physics, 2017 The effective manipulation of skyrmion motion introduces the technologically relevant possibility of skyrmion-based spintronics. Here we show how a magnetic skyrmion can be captured by a radially spatial gradient of the magnetic field.
