nanoparticles of mn0.5zn0.5-xcdxfe2o4 with x varying from x = 0.0 to 0.3 were prepared by wet chemical co-precipitation method. the structural and magnetic properties were studied by using x-ray diffraction (xrd), scanning electron microscope (sem), transmission electron microscopy (tem) and electron paramagnetic resonance (epr) technique. the lattice constant increases with increase in cd cont...

The electrodeposition of soft, high magnetic moment alloys has become the critical fabrication step in manufacturing of magnetic recording heads. The need for ultimately high magnetic moment alloys (2.4 T CoFe) and the electrodeposition process capable of delivering magnetic structures with dimension in the range of several tens of nanometers are the new tasks that have to be addressed if the f...

C66 We have measured the spin-polarized electron momentum density distributions (magnetic Compton profiles) of UGe2 using the synchrotron-based magnetic Compton scattering technique. The spin moment of UGe2 has been determined as -1.15 μB at 10 K with an applied magnetic field of 0.5 T. Compared with the saturated magnetization of +1.40 μB, we have determined the orbital moment at +2.55 μB. The...

We investigate the magnetic properties of epitaxial GaN:Gd layers as a function of the external magnetic field and temperature. An unprecedented magnetic moment is observed in this diluted magnetic semiconductor. The average value of the moment per Gd atom is found to be as high as 4000 micro(B) as compared to its atomic moment of 8 micro(B). The long-range spin polarization of the GaN matrix b...

We report the observation of a magnetic moment on vanadium embedded in copper. Using x-ray-absorption spectroscopy and x-ray magnetic circular dichroism we show that the vanadium atomic magnetic moment is strongly dependent on the formation temperature of the VCu alloy. The absorption spectra allow us to distinguish the electronic transitions which are the signature of the magnetic state from t...

Theory of the generation of magnetic moment field from resonant interaction of three high frequency electromagnetic waves in un-magnetized dense electron plasma is developed including the relativistic change of electron mass. It is shown that the inclusion of relativistic effect enhances the magnetic moment field. For high intensity laser beams this moment field may be of the order of a few meg...

We report magnetic field spectroscopy measurements in carbon nanotube quantum dots exhibiting fourfold shell structure in the energy level spectrum. The magnetic field induces a large splitting between the two orbital states of each shell, demonstrating their opposite magnetic moment and determining transitions in the spin and orbital configuration of the quantum dot ground state. We use inelas...

We have made a high-precision measurement of the magnetic moment of the Z + hyperon, using the precession of the spin in a conventional magnetic field. We have also made the first measurement of the magnetic moment of its antiparticle, the Z. In a separate experiment, we have demonstrated the precession of spin during channelling in a bent crystal, allowing a complementary measurement of the E ...

In the case of massless current quarks we find that the breaking of chiral symmetry usually triggers the generation of an anomalous magnetic moment for the quarks. We show that the kernel of the Ward identity for the vector vertex yields an important contribution. We compute the anomalous magnetic moment in several quark models. The results show that it is hard to escape a measurable anomalous ...
