The formula for Fe3O4 may be written as Fe2+O2−(Fe3+)2(O2−)3 in which the Fe ions exist in both +2 and +3 valence states in the ratio of 1:2. A net spin magnetic moment exists for each Fe2+ and Fe3+ ion. Th

Furthermore, the characters of the five irreducible repre- sentations of O are presented in Table 4, together with the characters of 2 + 1-dimensional irreps of SO(3). Applying the great orthogonality theorem, the decomposi- tion of the 2 + 1-dimensional representations of the rotation ...
The surface states of each d-dimensional [d-D] TI and TCI are termed anomalous because the surface states cannot be stabilized in a (d − 1)-D lattice model with the symmetries of the TI or TCI surface. In 3D TIs, AXIs, and Chern (QAH) insulators, the boundary anomaly and ...
Usually, this energy is found to be “small”, i.e., of the order of a few μeVs (or smaller) per atom in 3-dimensional systems. However, in lower dimensional systems, such as multilayers and nanoparticles, this energy could be higher by a few order of magnitudes. The dipolar term ...
The discovery of magnetism in ultrathin crystals opens up opportunities to explore new physics and to develop next-generation spintronic devices. Nevertheless, two-dimensional magnetic semiconductors with Curie temperatures higher than room temperature h
Besides, the magnetic microwire was simulated as a dipole moment and the dependence of its magnetic field and local magnetic field gradient to instantaneous velocity was evaluated. Moreover, to become closer to a biological situation, a stenosed arterial phantom was considered. In this phantom, ...
By varying the radius of the spherical surface, the cubed-sphere grid can be extended straightforwardly to a three-dimensional spherical shell domain. The local coordinates of three-dimensional cubed-sphere grid are (ξ,η,r)(ξ,η,r), where ξ,η∈[−π/4,π/4]ξ,η∈[−π/4,...
By using the three-dimensional morphologies of magnetic nanoparticles, provided by electron tomography, as the input for finite element micromagnetic simulations (Section 2.20.4), it is now possible to compare experimental observations and theoretical predictions directly. Differences between observed and ...
