Using numerical simulations, we explore the static and dynamic response of hopfions to an external magnetic field in cylindrical and toroidal nanorings. Results evidence that the nucleation and stability of hopfions are intricately linked to geometry

We have used angled magnetron sputter deposition with and without sample rotation to control the magnetic anisotropy in 20 nm NiFe films. Ferromagnetic resonance spectroscopy, with data analysis using a Bayesian approach, is used to extract material

Abstract The relaxation time under zero field reflects the memory retention capabilities of single‐molecule magnets (SMMs) when used as storage devices. Intermolecular magnetic dipole interaction is ubiquitous in aggregates of magnetic molecules an

Abstract Soft ferromagnetic permalloy (NiFe) thin films are promising for applications in spintronic devices because of their constituent electrical and magnetic properties. Electron beam evaporation and sputtering techniques have been used to deposi

At elevated temperatures, the Landau–Lifshitz–Bloch equation stands as a cornerstone in elucidating micromagnetic phenomena, particularly in the context of materials utilized for the digital storage of information. The Landau–Lifshitz–Bloch m

Magnons, recognized as the quanta of spin waves, offer a pathway for transmitting information without the need for electron motion, thus emerging as a leading candidate for the next generation of low-power electronics. Firstly, this study gives an ov

This dissertation is focused on ferromagnetic, multiferroics, and two-dimensional (2D) perovskites, exploring different unique collective magnetic and ferroic characters: (1) ferromagnetic thin film Co/Pd multilayers, (2) BaTiO3-BiFeO3 (BTO-BFO) a ma

The Landau–Lifshitz–Gilbert (LLG) equation models the temporal evolution of magnetization in continuum ferromagnets. The LLG equation has a nonconvex constraint and is highly nonlinear. In this paper, we will use the Fourier-spectral method for a
