The 23Na nuclear quadrupole coupling constant is calculated for six compounds of the alpha -NaFeO2 type, namely NaInO2, NaCrO2, NaTiO2, NaTlO2, NaScO2 and NaAlO2. The authors assume point-charge distribution at the lattice sites and take into account

EFG calculations (dipolar contributions included) are reported of the 23Na nuclear quadrupole coupling constant in NaInS2, NaInSe2, NaCrS2 and NaCrSe2 which yields small polarizability values of 0.1 A3 and 0.08 A3 for sulphur and selenium respectivel

We report on the presence of magnetic iron oxides in the migratory ant Pachycondyla marginata. Magnetic particles were extracted from different parts of the ant (head, thorax and abdomen) using magnetic precipitation methods. Electron spectroscopic i

Magnetotactic bacteria are present in fresh water and marine sediments of Fortaleza, Brazil, situated close to the geomagnetic equator. Both South-seeking and North-seeking bacteria are present in roughly equal numbers in the same samples. This obser
