A relativistic version of Pauli paramagnetism for n − p − e system inside a strongly magnetized neutron star has been developed. An analytical expressions for the saturation value of magnetic field strength for each of these constituents at which they are completely polarized have been obtained. From the fully polarized configuration of electronic component, an upper limit for neutron star magn...

Quasielectrons and quasiholes in the fractional quantum Hall liquids obey fractional (including nontrivial mutual) exclusion statistics. Their statistics matrix can be determined from several possible state-counting scheme, involving different assumptions on statistical correlations. Thermal activation of quasiparticle pairs and thermodynamic properties of the fractional quantum Hall liquids ne...

Skyrmions represent topologically stable field configurations with particle-like properties. We used neutron scattering to observe the spontaneous formation of a two-dimensional lattice of skyrmion lines, a type of magnetic vortex, in the chiral itinerant-electron magnet MnSi. The skyrmion lattice stabilizes at the border between paramagnetism and long-range helimagnetic order perpendicular to ...

We use tunable dipolar-interactions between the spins of nitrogen-vacancy (NV) centers in diamond to rotate a crystal. Specifically, we employ cross-relaxation electronic spin pairs NV trapped enhance anisotropic paramagnetism and thus increase associated torque. Our observations open path towards mechanical oscillators detect paramagnetic defects that lack optical transitions, investigation an...

Through magnetic linear dichroism spectroscopy, the magnetic susceptibility anisotropy of metallic single-walled carbon nanotubes has been extracted and found to be 2-4 times greater than values for semiconducting nanotubes. This large anisotropy can be understood in terms of large orbital paramagnetism of metallic nanotubes arising from the Aharonov-Bohm-phase-induced gap opening in a parallel...

U2T2X compounds (Mo2FeB2 structure type, T transition metal, X p-element), exhibiting wide range of magnetic properties from weak paramagnetism to 5f-antiferromagnetism, have been checked for hydrogen absorbtion properties. Besides U2Co2Sn hydrides, which have already been reported, U2Ni2SnH1.8, U2Ni2InH1.9, U2Co2InH1.9, and U2Fe2SnH1.9, have been synthesized. Hydrogenation leads to the enhance...

A successful observation and analysis of the Zeeman effect on the lambda approximately 1.54 microm photoluminescence band in Er-doped crystalline MBE-grown silicon are presented. The symmetry of the dominant optically active centers is conclusively established as orthorhombic I(C(2v)) with g axially approximately 18.39 and g radially approximately 0. In this way the long standing puzzle as rega...

In order to prominently investigate the effects of the surface spin on the magnetic properties, the weak magnetic ZnLa0.02Fe1.98O4 nanoparticles were chosen as studying objects which benefit to reduce as possibly the effects of interparticle dipolar interaction and crystalline anisotropy energies. By annealing the undiluted and diluted ZnLa0.02Fe1.98O4 nanoparticles at different temperatures, w...

ZnFe2O4 nanocomposites have been prepared by a simple co‐precipitation method. The prepared samples were characterized by Scanning Electron Microscopy (SEM), Powder X‐ray Diffraction (XRD), Energy Disperse X‐ray Analysis (EDX), Transmission electron microscopy (TEM) and UV‐visible absorption spectral techniques. Conductivity measurements show a transition from ferrimagnetism to...

The magnetic properties of electrons in a metal are investigated for the case of an arbitrary dispersion law. The energy levels of a quasiparticle for an arbitrary dispersion law in a magnetic field are found, and the magnetic moment of a gas of such quasiparticles is computed, spin paramagnetism being taken into account. It is shown that the periods and amplitudes of oscillations are determine...
