1.2 Appendix 4.2: Using a classical tokamak formula for the magnetic field A classical formula for tokamak magnetic fields is $$\begin{aligned} {\textbf{B}}=\nabla \varphi \times \nabla \psi + I(\psi ) \nabla \varphi \end{aligned}$$ (131) where \(\psi =\psi _p/2\pi\) is ...
The most commonly used soft magnetic oxides are the ferrites of the spinel structure, having the formula TO·Fe2O3 where T is a divalent transition ion. In this structure the Fe+3 and T+2 ions can occupy two types of sites having different oxygen coordination: tetragonal “A” sites and...
The force between two magnetic poles is similar to the force that exists between two charges. In both cases, the force can be one of attraction or repulsion. In the 1780s, Charles-Augustin de Coulomb, a French physicist, developed the mathematical formula for calculating the force for either...
Although it has different formulae for (generic) network and lattice models, the basic ideas are the same. A quasi-1D sample is divided into layers with normals along the quasi-1D direction. The amplitudes of an energy-eigenstate on different layers are related by the Schrodinger equation. A...
functions61. Based on the real-space Hamiltonian in the maximally-localized Wannier functions basis, we evaluated the spin current dipole and spin conductivity of MSHE within the linear response theory using the Kubo formula, as implemented in the Wannier-Linear-Response code26. We also calculated...
