We use a method which combines the discretized path-integral representation (DPIR) with the double-chain approximation (DCA) to study the thermodynamic properties of an S 1 antiferromagnetic Heisenberg chain (AFHC) with both uniaxial and non-uniaxial single-ion anisotropy. The magnetization in the presence of an external magnetic field, the zero-field magnetic susceptibility and the magnetic ...
Both shipboard and shore-based magnetic studies of Ocean Drilling Program (ODP) Leg 208 sediments produced poor-quality irectional data. A noisy inclination signal and a pervasive declination bias demonstrate that the sediments had been remagnetized nd/or deformed. In an attempt to characterize any deformation, we carried out anisotropy of magnetic susceptibility (AMS) experments on a suite of ...
we used dbsa and nano-magnetic for the synthesis of amido alkylnaphtols.
We have determined the azimuth of bottom-current flow in drift deposit sediments recovered at ODP Sites 1095 and 1101, Antarctic Peninsula, using paleomagnetic reorientation of anisotropy of magnetic susceptibility (AMS) ellipsoids. A total of 38 cores from the two ODP sites have been measured, providing spatial and directional information on the physical record of the ACC (Antarctic Circumpola...
Magnetic fabric analyses, gravity inversion associated with chemical U-Th-Pb dating and structural observations are carried out to elucidate relationships between faulting and magmatic processes. This multidisciplinary study has been undertaken on Late Carboniferous plutons, situated in the southern part of the Variscan French Massif Central (FMC). The Glénat, Omps and Boisset plutons crop out ...
We report on the single crystal growth of the ferromagnetic Kondo lattice system CeRuPO using a Sn flux method. Magnetic susceptibility and electrical resistivity measurements indicate strong anisotropy of this structurally layered compound. They evidence that the magnetic moments order ferromagnetically along the c-direction of the tetragonal unit cell, whereas the crystal electric field (CEF)...
By phenomenological Landau analysis, it is shown that a scalar order parameter with the pointgroup symmetry Γ1g explains most properties associated with the phase transition in PrFe4P12 at 6.5 K. The scalar-order model reproduces magnetic and elastic properties in PrFe4P12 consistently such as (i) the anomaly of the magnetic susceptibility and elastic constant at the transition temperature, (ii...
We present a study on the magnetic anisotropy and magnetization reversal of Fes110d islands grown on Al2O3 versus the island size, the island size distribution, and the magnetic interaction between islands. For small islands magnetically connected via a polarizable capping layer, the samples behave as a uniform film with an induced uniaxial in-plane anisotropy. Magnetically isotropic samples ar...
2014 The elastic constants, magnetic susceptibility, refractive index and density are reported for p,p’-diheptylazobenzene. The behaviour of the elastic constants of this non polar compound is very similar to that of related polar compounds. The anisotropy of both the static and the highfrequency permittivity is proportional to the anisotropy of the susceptibility, as observed earlier for the h...
