In particular the Mn atoms in the exohedral SinMn+ (n=6–10) clusters have local magnetic moments of 4 μB or 6 μB and can be considered as magnetic copies of the silicon atoms. Opposed to other 3d transition-metal dopants, the local magnetic moment of the Mn atom is not ...
In subject area: Chemistry A Nuclear Magnetic Moment refers to the property of a nucleus that arises from its interaction with magnetic fields, with the lowest moment being the magnetic dipole moment followed by the magnetic octupole moment. The values of nuclear moments are determined through a ...
Clearly, the magnetic moment approaches the free atom value as the dimensionality is decreased. The spin densities of 7layer Fe(001) and Ni(001) slabs are given in Fig. 1. For Fe(001),8l the positive spin density dominates most of the space around the Fe atoms, with only small ...
In subject area: Computer Science A magnetic moment refers to the magnetic properties of a material, which are caused by the motion of electrons in atoms. The motion can be either spin or orbital, and it results in a magnetic moment associated with the electron. The magnetic moment is expres...
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...
For over 100 years, the group-theoretic characterization of crystalline solids has provided the foundational language for diverse problems in physics and chemistry. However, the group theory of crystals with commensurate magnetic order has remained incom
1–5 The correlation between atom size, by various measures, and magnetic moment has long been noted.6 This correlation is readily seen by comparing the atomic concentrations of the first, second and third transition series elements as shown in Fig. 1, where the densities for the second and ...
Electron magnetic resonance occurs when an electromagnetic wave of suitable frequency (usually in the microwave region) interacts with the sample immersed in an applied magnetic field and causes the inversion of the spin (and thus of the magnetic moment) of the unpaired electrons so that a certain...
