Wonderland of frustration: Magnetic moments and itinerant electrons on the pyrochlore lattice
… we investigate the effects of frustration in magnetic systems on the pyrochlore lattice, looking at both the conventional frustrated magnetism as well as a less studied form of frustration known as kinetic frustration. We start at half-filling, where the magnetic moments in a Mott insulator …

Quantifying Magnetic Moments And Susceptibilities Of Small Cylindrical And Spherical Objects In Mri
… a method for accurately quantifying effective magnetic moments and susceptibility of either cylindrical or spherical-like small objects from magnetic resonance imaging (MRI). A standard 3D gradient echo sequence with only one echo time is intended for our approach to measure the effective …

A study of coordination compounds of nickel with some diamines.
… metals can exist in two form with differing magnetic moments. As the paramagnetic susceptibility arises largely from the unpaired electrons present in the molecule, this means that the two classes of compound for any metal must have differing numbers of unpaired electrons. The first …

Electromagnetic properties of baryons from lattice QCD
Electromagnetic properties of the octet and decuplet baryons are calculated in quenched QCD on a 20 ³ x40 lattice with a lattice spacing of 0.128 fm using the fat - link irrelevant clover ( FLIC ) fermion action. FLIC fermions enable simulations to be performed efficiently at quark masses as low as …

Density-Functional Theory+Dynamical Mean-Field Theory Study of the Magnetic Properties of Transition-Metal Nanostructures
… (DMFT) approaches are applied to study the magnetic properties of transition metal nanosystems of different sizes and compositions. In particular, in order to take into account dynamical electron correlation effects (time-resolved local charge interactions), we have adopted the DFT+DMFT …

Element-resolved ultrafast magnetization dynamics in ferromagnetic alloys and multilayers
… the quenching of the magnetization of a ferromagnetic metal on a sub-picosecond timescale after laser excitation, is still only incompletely understood, despite a large body of experimental and theoretical work performed since the discovery of the effect more than 15 years ago. Time- and …

Interlayer exchange coupling in magnetic multilayers
… discovery of the exchange coupling between ferromagnetic layers separated by nonmagnetic spacer layers has stimulated a great deal of interest recently. We present a theoretical study of the interlayer coupling in magnetic multilayers using two theoretical approaches. One such approach is to …

PROOF-OF-PRINCIPLE TEST FOR AN EXPERIMENT FOR SHORT-LIVED PARTICLE DIPOLE MOMENTS AT LHC
The magnetic (MDM) and electric (EDM) dipole moments of fundamental particles serve as powerful probes of the Standard Model and of possible extensions that introduce new sources of CP violation. A permanent EDM would constitute clear evidence of physics beyond the Standard Model, while magnetic …
