Second order perturbed Heisenberg Hamiltonian of Fe₃O₄ ultra-thin films

Ceylon Journal of Science, 2018
Due to the wide range of applications, theoretical models of Fe3O4 films are found to be important. Ultra thin Fe3O4 films with ferrite structure have been theoretically investigated using second order perturbed modified Heisenberg Hamiltonian.

Magnetic Anisotropy in Heterobimetallic Complexes

Inorganic Chemistry, 2019
Control of spin-orbit coupling enables the targeted modulation of coherence, catalytic, and magnetic properties in metal complexes. In this Forum, we describe our approach to exerting synthetic control over spin-orbit coupling by using heavy diamagnetic main-group metals as an external source of spin-orbit coupling.

Formation of Magnetic Anisotropy by Lithography [PDF]

Scientific Reports, 2016
AbstractArtificial interface anisotropy is demonstrated in alternating Co/Pt and Co/Pd stripe patterns, providing a means of forming magnetic anisotropy using lithography. In-plane hysteresis loops measured along two principal directions are explained in depth by two competing shape and interface anisotropies, thus confirming the formation of interface

Micromagnetic studies of three-dimensional pyramidal shell-structures [PDF]

, 2010
In this article we present a systematic, numerical analysis of the magnetic properties of pyramidal-shaped core-shell structures in a size range below 400nm.These are three dimensional structures consisting of a ferromagnetic shell which is grown on top ...

Self‐Sintering Ionogel Binder for Flexible, Recyclable, and Healable Printed Giant Magnetoresistive Sensors

Advanced Functional Materials, EarlyView.
ABSTRACT Electronic waste has emerged as a major environmental challenge, driven by the massive consumption and a limited lifetime of modern electronic devices, stimulating the development of sustainable electronics. Here, an all‐biomaterial gelatin‐choline‐citric acid ([Ch][CA]) ionogel is developed as an active binder to realize self‐sintered ...

Orbital Geometry‐Governed Response of Pressure‐Tunable Quantum Defects in hBN

Advanced Functional Materials, EarlyView.
Defects in hBN act as ultrasensitive quantum manometers when the energy of the intradefect optical transitions is modified by lattice compression. The orbital geometry of the electron wave functions governs how electron hopping and Coulomb interactions react uniquely to the reduction of the van der Waals gap and in‐plane compression, leading to robust ...

Smagorinsky constant in LES modeling of anisotropic MHD turbulence

, 2008
Turbulent fluctuations in magnetohydrodynamic (MHD) flows can become strongly anisotropic or even quasi-2D under the action of an applied magnetic field. We investigate this phenomenon in the case of low magnetic Reynolds numbers.

Crystallographic preferred orientation, magnetic and seismic anisotropy in rocks from the Finero peridotite, Ivrea-Verbano Zone, Northern Italy – Interplay of anisotropy contributions from different minerals [PDF]

, 2020
Mineral alignment can provide valuable information on a rock's geological history. Many structural, tectonic, or geodynamic studies rely on determining the preferred orientation of rock-forming minerals, either by direct texture determination or using ...
