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. There are antiparallel spin–coupling interactions between the Fe...
Moment of inertia in the electron band structure for bulk fcc Co strained along thezaxis. The magnetic moment is also inzdirection. The colour and the intensity indicates the sign and value of the inertia contribution (blue −ι < 0; red −ι > 0; yellow −\(\iota \approx...

In this respect, due to low magnetic damping properties, among many candidates for half-metallic ferromagnetic electrodes6,7full-Heusler materials occupy one of the leading position8,9,10,11. Using a general X2YZ chemical formula, where X and Y denote transition metals while Z denotes one of ...

The anomalous chromomagnetic moment of the top quark arises from one loopcorrections to the vertex $\\bar t t g$. We give explicit formulae for thisanomalous coupling in the framework of the standard model, the two Higgsdoublet model and the minimal supersymmetric standard model. We compare ...
(primarily magnetic fields) measured by satellite missions during varying driving and activity conditions. Reconstruction of the global structure from data is very challenging because of the data paucity with less than a dozen probes available for in-situ observations at any moment. However, modern ...
However, in the presence of a magnetic field, there will be a net statistical alignment of the magnetic moments analogous to a paramagnet but with a higher magnetic moment, which can be up to 104 times larger than that of an atomic paramagnet. To name some examples, superparamagnetic iron ...
As we discussed in Section 3.1., the spin magnetic moment of Ti is very large and contributes majorly in the total magnetic moment, while the small-spin magnetic moment of the Rh, Ge, and Y atoms make almost no contribution. Normally, Slater–Pauling rules can be divided into three types...
The magnetometer gives a value of σ, the magnetic moment per gram from which magnetization M is obtained from the formula: M=4πρσ where ρ is the density of the particles in the test sample, σ is the magnetic moment in emu/g and M is the magnetization of the particles in gauss ...
