This simulation is based on the direct implementation of the time-dependent Schrödinger equation in three dimensions. The expectation value of the quantum magnetic dipole operator is calculated as a function of the applied magnetic field strength of a time-oscillating magnetic field. These expectation values are used to calculate the linear and nonlinear magnetic susceptibility of a torus. |

In this work, we show that such an arrangement allows the controlled RF-heating of small bodies (typically for annealing or curing of integrated circuits). |
Research Article | Volume 4, Issue 1 DOI: 10.35840/2631-5068/6513Hydrogen Annealing on the Structural, Optical and Magnetic Properties of Yb-Doped Zno Diluted Magnetic Semiconductor Thin FilmsWeibin Chen, Xuechao Liu, Shiyi Zhuo, Jun Chai, Tingxiang Xu and Erwei ShiAbstractThe structural, optical and magnetic properties are characterized by using different measurement techniques. All the annealed Zn0.985Yb0.015O thin films show room-temperature ferromagnetism and the saturation magnetization exhibits a similar dependency on the annealing temperature. |
Research Article | Volume 4, Issue 1 DOI: 10.35840/2631-5068/6512Power-Invariant Magnetic System ModelingGuadalupe G Gonzalez and Mehrdad EhsaniAbstractIn this paper, we present an alternative to modeling magnetic systems using a more consistent approach to lumped parameters. The model we introduce is consistent with other energy system models and allows the engineer to draw analogies from other energy systems to gather insights and a clearer understanding of magnetic systems which up to now has not been available. First, the justification for our new approach and a literature review of other models based on lumped parameters is presented in order to highlight the differences between those and our model. |

This is a true three-dimensional simulation based on the direct implementation of the time-dependent Schrödinger equation. We demonstrate that the expectation value the quantum magnetic dipole operator returns results consistent with a classical electron in a loop under the influence of a magnetic field. |
