查询词典 magnetic moment

The Aharonov-Bohm scattering of relativistic particles with an anomalous magnetic moment is studied. Exact solutions are obtained. The effect of the anomalous magnetic moment on the scattering of polarized particles turns out to be rather unexpected.

Instead they have an improved idea which is to apply a suitable magnetic field and exploit the anomalous magnetic moment of the Lambda baryons to measure simultaneously their polarization along three independent axes turning a passive measurement -one involving a check of the decay kinematics of the Lambda particles- into an active one -directly figuring out the polarization.

I hope that this text sheds a new light on some aspects of the Driac theory which to my knowledge have not yet found their way into textbooks, for example, a rigorous treatment of the nonrelativistic limit, the supersymmetric solution of the Coulomb problem and the effect of an anomalous magnetic moment, the asymptotic analysis of relativistic observables on scattering states, some results on magnetic fields, or the super symmetric derivation of solutions of the mKdV equation.

Calculated results showed that in the Ni2MnIn phase, the atomic orbital magnetic moment of Mn dominates the unit cell's magnetic moment, i. e., about 85% of the total magnetic moments of unit cells. The contribution of Ni to the total cell's magnetic moments is about 15%. As to the In atoms, they show a weak diamagnetism in both phases. In particular, the phase transformation of tetragonal martensite results in the decrease in Fermi energy of Ni2MnIn unit cells by 0.495 eV.

The main contents of this dissertation are as follows:(1) According to involved theories of ferromagnetics, the microscopic mechanism of domain structure is analyzed systematically; through the movement variation of domain structure, that is the movement of domain wall and rotation of magnetic moment, the magnetization process is illustrated in an applied magnetic field. Meanwhile, by the use of energy methods, a study is performed on influencing factors of domain movement including stress, dope, scattering field, etc. The influence of various energies is dealt with on the magnetic behavior and parameters of ferromagnetic material; the corresponding theories of the spontaneous magnetization and technical magnetization are also discussed.

III Investigations of ferromagnetic alloy films by XMCD1. By using XMCD and SQUID magnetometry, the spin and orbital moments of Fe and Co in the Co_(0.9)Fe_(0.1)(50nm) are studied. Compared with single-element film, the spin moment of Co remains constant while that of Fe reduced from 1.98 to 1.63μB. The contributions of different elements in the film is, m_ : m_ - 10.5 : 89.5. The average magnetic moment (1.90μB) determined by XMCD is in agreement with that (1.82μB) obtained from SQUID measurements. Utilizing XMCD spectra in-plane element-dependent magnetic anisotropy in Co_(0.9)Fe_(0.1) films has been investigated. Apart from known field-induced easy axis during film growth, a soft axis perpendicular to it was observed, and hard axes are 66° away from the easy axis.
