2020-3-22  Magnetism is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Magnetism is one aspect of the combined phenomenon of electromagnetism.The most familiar effects occur in ferromagnetic materials, which are strongly

## Magnetic ordering - ScienceDirect

The ordering of magnetic moments in about 60 compounds containing M=Cr, Mn, Fe, Co, Ni, Pd, rare earths or U is analyzed by the self-coordination numbers of nearest, second and third neighbor positions T 1, T 2, T 3 and the ratio r=y/x of the equivalent positions x and remaining positions y.The plot of T 1, T 2 values for primitive cubic or hexagonal, face-centered or body-centered cubic ...

## Magnetic Order in Superconductors - NIST

The magnetic ordering temperatures are all low, ~1K, and thus it was argued that electromagnetic (dipolar) interactions should dominate the energetics of the magnetic system. For materials where these interactions favor antiferromagnetism the magnetization averages to zero on the length scale of a unit cell ( a ), which results in a weak ...

## Magnetic Ordering - an overview ScienceDirect Topics

Both chemical and magnetic ordering are accompanied by distortion of the crystal. For example, when an alloy of Fe and Pt of equiatomic composition is cooled down from a high-temperature solid-solution, a chemical ordering begins to occur in the fcc structure at 1280 °C to form the layer-by-layer arrangement shown in Figure 24, the L1 0 structure. As this structure is of tetragonal symmetry ...

In the antiferromagnetic state, the lattice formed by magnetic atoms is divided into two or more equivalent sublattices, each presenting a spontaneous magnetization in a certain direction. The interaction between the dipoles causes a magnetic ordering such that the vector sum of the spontaneous magnetization of the sublattice vanishes, which ...

## Magnetic structure - Wikipedia

2020-6-12  Magnetic structures. Most solid materials are non-magnetic, that is, they do not display a magnetic structure. Due to the Pauli exclusion principle, each state is occupied by electrons of opposing spins, so that the charge density is compensated everywhere and the spin degree of freedom is trivial.Still, such materials typically do show a weak magnetic behaviour, e.g. due to Pauli ...
