The magnetic moment gets larger in an applied field either because the domain walls move (mostly at low fields) or because the magnetization within the domains rotates (mostly at higher fields). See Figure 9.21(b). Only at very large fields do all the domains become oriented in the same ...

Magnetic materials are materials studied and used mainly for their magnetic 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 fie...
The cobal + magnetic moment is 0.2μ B for both compounds. The easy magnetization direction lies on the hexagonal plane for Ho 4Co 3 while for Er 4Co 3 there are 2 anisotropy directions. Exchange interactions between rare-earth ions of both sites are very weak compared with the total ...

This time a hf/ dipolar coupling between the electronic magnetic moments and the muon magnetic moment is utilized after a muon stops in the sample. The resulting local magnetic field Bm at the muon site affects the mSR asymmetry A(t) that is proportional to the muon polarization precessing in...
[NiCl4]^(2-), oxidation number of Ni, x-4=-2 :. x=+2, Ni((28))[Ar]3d^8, 4s^2 sp^3-hybrid orbitals, tetrahedral Since, Cl^(-) is a weak ligand, thus unpaired electrons are not paired. Lone pairs from 4Cl^(-) are accommodated in four sp^3 hybrid o
Magnetization process of noninteracting ferromagnetic cobalt nanoparticles in the superparamagnetic regime: Deviation from Langevin law It allows us to determine the magnetic moment of the particle in the low-field region, and then the effective anisotropy from the approach to the ...

case of lanthanides is either exchange coupling between n.n., albeit weak because of the shielded character of the 4f electron orbitals, and long-range dipolar interaction, which may be relevant at very low temperatures because of the large orbital moment in many of the lanthanide substitutions....
Research in Er-doped materials is of high technological importance and has resulted in development of Er-doped fiber amplifiers (EDFA) and Er-basedfiber lasers[1–4]. In addition, the unpaired 4felectrons produce a magnetic moment and have madeEran important constituent of permanentmagnetic alloys...
