The magnetic moment of an electron spin is considered as one unit of magnetic moment. This is called Bohr magneton (BM) and has a value of 9.27×10−24 Am2 or JT−1. The iron atom as part of the crystal has a magnetic moment of 2.2 BM. Cobalt and nickel have magnetic moments ...
ferrimagnetism, spin-glass behavior, or paramagnetic behavior. Equally important is the fact that the magnetic moment per atom in the solid is often less than that of the individual atoms. Understanding of the origin of these properties can help in improvingmagnetic propertiesof materials. This is...

The magnetic moment of the Hydrogen atom in a stationary state expresses as an integral of the corresponding electric current. The integral splits in two summands, of which one is responsible for diamagnetism resulting in the Langevin formula for diamagnetic susceptibility, and the second one is ...
properties. The magnetic response of a materials is largely determined by the magnetic dipole moment associated with the intrinsic angular momentum, or spin, of its electrons. A material’s response to an applied magnetic field can be characterized as diamagnetic, paramagnetic, ferromagnetic or ...
All things in the world show some kind of magnetism. But the strength of the magnetism is very different between things. Based on the properties of magnets, we have five big groups: ferromagnetic, paramagnetic, diamagnetic, ferrimagnetic, and antiferromagnetic. ...

of interstitial oxygens are performed in the supercell model using the transformation matrix (2 0 0, 0 2 0, 0 0 1) of the conventional unit cell comprising 120 atoms plus an additional interstitial oxygen atom41. The reciprocal space integration was performed by sampling the Brillouin zone ...
Using the macroscopic equation of motion of the magnetic moment (the Landau–Lifshitz equation; see SP 2, (69.9)), derive the magnetic permeability tensor for a uniformly magnetized uniaxial ferromagnet of the easy-axis type, in the absence of dissipation (L. D. Landau and E. M. Lifshitz,...
The intrinsic magnetic moment of these case A metals lowers the effect of bond compression on the activation energy for solid state diffusion. Such lowering of the energy follows from the increased exchange interaction during bond compression, which counters the electronic repulsion to lower the ...
