magnetic moment

An MRI term for a measure of the net magnetic properties of an object or particle, which is a sum of the intrinsic spins of the nuclei that have an associated magnetic dipole moment interacting with a magnetic field.

These can be attributed qualitatively to a range of interactions between the charge of the electrons, their magnetic moment, their localization within the crystals and their atomic orbitals.
The influence of the level of the external magnetic field and the length of the core on its magnetic moment. Due to the axial symmetry of the field, the magnetic moment vector [??] of the core under consideration has only an axial projection in cylindrical coordinates
The relationship between the magnetic moment and the angular momentum is called the "gyromagnetic ratio" and has the value "e/2m".
Neutron diffraction studies of the B2-ordered Fe-Al alloys with Al concentrations of 34-43 at.% confirmed the existence of spatial correlations between the magnetic moments with a coherence length of about 5 nm, which were interpreted in terms of spin density wave.

High concentrations of defects were observed in all the samples, indicating the possible role of defects in inducing magnetic moments and mediating ferromagnetism.
Figure 4S, https://www.raccefyn.co/index.php/raccefyn/ article/downloadSuppFile/422/1993, and table 8 show how M10-M40 samples achieved the M maximum value at 129K approximately, and it is a result of the irregular particle size (figure 2S, https://www.raccefyn.co/index.php/raccefyn/ article/downloadSuppFile/422/1990), a growing presence of the hematite phase and the resistive effect of the HDPE matrix which hinders the magnetic moments alignment of the magnetite particles exposed to an external magnetic field (Kong, et al., 2010).
And now, scientists working with the Baryon Antibaryon Symmetry Experiment (BASE) have (http://www.nature.com/articles/ncomms14084) achieved a sixfold improvement in accuracy of the magnetic moment of the antiproton.
The essence of magnetic domain is an ordered arrangement of atomic magnetic moment in a small region, and its formation and existence are determined by interaction of various energies.
It is concluded about magnetic properties of amorphous alloy [Co.sub.87][Nb.sub.46][B.sub.15], that there is a difference in their magnetic moment because of a low property of ferromagnetic phases.
[absolute value of ([P.sup.m])] denotes the magnitude of the magnetic moment. (x, y, z) denotes the position of the target.
For antiferromagnetic, magnetic moment of these two sites have equal magnetic moment and for ferrites it is unequal.
