Sakhalin has been affected by several phases of Cretaceous and Tertiary deformation due to the complex interaction of plates in the northwest Pacific region. A detailed understanding of the strain is important because it will provide constraints on platescale processes that control the formation and deformation of marginal sedimentary basins. Anisotropy of magnetic susceptibility (AMS) data wer...

We have determined the magnetic properties of single-crystalline Au nanorods in solution using an optically detected magnetic alignment technique. The rods exhibit a large anisotropy in the magnetic volume susceptibility (Δχ(V)). Δχ(V) increases with decreasing rod size and increasing aspect ratio and corresponds to an average volume susceptibility (χ(V)), which is drastically enhanced relative...

hired is a large gold prospecting area which is located in south khorasan province, in the east of iran. gold mineralization is found in 4 target areas covering about 24 km2. the host rocks are mainly tertiary volcanics, some jurassic and cretaceous sediments. sub-volcanic rocks are of magnetite series (gabbros to diorite) and ilmenite series (granite-granodiorite-monzonite) which have intruded...

a preliminary palaeomagnetic results from basalt outcrops in northeast lebanon is reported. the remanence carrier of the characteristic magnetisation is magnetite.  both variations of susceptibility and anisotropy directional data show that the measured directions of thermoremanent magnetisation (trm) are representative of the ambient field at the time of cooling of these basalts through their ...

â â â  â  â â â â â â â  abstract â  the abtalkh formation in the kopeh-dagh basin in northeastern iran with an age of late cretaceous (turonian – santonian) is selected to evaluate resolution of magnetic susceptibility for assessing sea level fluctuations. thirty-nine shale samples were collected and studied for magnetic susceptibility and palynology. assuming the average ms magnitude as the...

Magnetic behavior of a spin-1 Heisenberg dimer is analysed in dependence on both uniaxial single-ion anisotropy and XXZ exchange anisotropy in a zeroas well as non-zero longitudinal magnetic field. A complete set of eigenfunctions and eigenvalues of the total Hamiltonian is presented together with an exact analytical expression for the Gibbs free energy, longitudinal magnetization, longitudinal...

A model providing a semi-quantitative account for the magnetic behavior of Co nanoparticles embedded in a CoO matrix is presented. The results confirm that exchange coupling at the interface between FM and AFM nanostructures, could provide an extra source of magnetic anisotropy, leading to thermal stability of the FM nanoparticles. It is shown that perpendicular coupling between the AFM and FM ...

PURPOSE To investigate the effects on quantitative susceptibility mapping (QSM) and susceptibility tensor imaging (STI) of the frequency variation produced by the microstructure of white matter (WM). METHODS The frequency offsets in a WM tissue sample that are not explained by the effect of bulk isotropic or anisotropic magnetic susceptibility, but rather result from the local microstructure,...
