We have theoretically investigated the spin Seebeck effect (SSE) in a normal metal (NM)/paramagnetic insulator (PI) bilayer system. Through linear response approach, we calculated thermal pumping from PI to NM and backflow current PI, where spin-flip scattering via interfacial exchange coupling between conduction-electron localized is taken into account. found finite appears at interface under ...

Some calculations of the electric field derivative of the spin-spin coupling constant on molecules in the series CH3F, CH3Cl, CH3Br, CH3I, CH4, CH3Li, CH3Na and CH3K have been presented. The data is broken down into the 4 terms of the Ramsey theory: Fermi contact (FC); diamagnetic spin-orbit (DSO); paramagnetic spinorbit (PSO) and spin-dipolar (SD). The FC term is seen to dominate all the calcu...

The diamagnetism of biological tissues reduces the homogeneity of the magnetic field and may limit the number of samples in multi-sample gradient-recalled echo (GRE) experiments. This study aims to 1) evaluate the magnetic field distortions and signal loss artifacts in GRE images of proximal water samples, and 2) develop a passive shimming device to overcome this limitation. The magnetic field ...

In the retrospective dose assessment of individuals potentially exposed to ionizing radiation after an accident, dosimetry with inert materials can complement or be used as an alternative to biodosimetry assays. Dosimetry based on physical methods such as Electron Paramagnetic Resonance (EPR), Thermoluminescence (TL) or Optically Stimulated Luminescence (OSL) provides measurements of absorbed d...

Several reviews concerning the EPR of the paramagnetic transition-metal ions in crystals are now available, either as periodic reports published in the Magnetic Resonance Review, or in books [1,2,3] and review papers [4, 5]. Such paramagnetic centers are usually observed in the as grown crystals, the paramagnetic state being the normal valency state of the impurity in the crystal-host lattice. ...
