WebApr 10, 2024 · Because the perpendicular magnetic field broke the inversion symmetry of SOT generated from the middle Pt layer, it could be used to control the switching current. Our results prove that the additional uniform and perpendicular magnetic field can enhance the controllability of the magnetization state in case of multi-level SOT-induced ...

The application handles: Gravity inversion for the recovery of residual density (g/cc). Scalar magnetic inversion (MAG) for the recovery of susceptibility (SI).
WebMar 30, 2024 · The main source for the uncertainty of the inversion of magnetic data is the non-uniqueness of potential data, which means that there are infinite mathematic solutions for one set of magnetic data measured on a surface. Magnetic anomaly is affected jointly by the source scale, shape, depth and magnetization. In 3D inversion of magnetic data ... WebMar 8, 2024 · The difficulty of 3-D magnetic inversion is to use 2-D magnetic anomaly data to obtain 3-D magnetic susceptibility structure. The contribution of the underground medium to the magnetic anomaly decreases rapidly with the increase of the depth, which leads to the rapid attenuation of the inversion resolution with the depth. In this article, …
WebInvariance with respect to anti-inversion is the defining symmetry of the linear magnetoelectric (ME) effect included in 58 of 122 magnetic crystal classes, 19 of which prohibit higher-order (non-linear) contributions to the free-energy. In ME compounds, expectation values of some atomic magnetic tensors are invariant with respect to anti ...
