The magnetic properties of the ferroic (1-x)PbFe[sub 2/3]W[sub 1/3]O[sub 3]–xPbTiO[sub 3] system with various compositions in the range x∈(0,0.50) were investigated. A magnetodielectric coupling is proved by an anomaly of the magnetic hysteresis loop found in the Curie range of temperatures for the relaxor PbFe[sub 2/3]W[sub 1/3]O[sub 3] ceramic. Two types of superexchange magnetic interactions and a succession of magnetic transitions with Néel temperatures dependent on the composition were found in the system. The present results confirm the hypothesis of a relationship between the magnetic properties and the nanopolar ordering in the relaxor–ferroelectric system. © 2003 American Institute of Physics.

    We derive rules for bonding at interfaces between Si and ionic oxides so that they satisfy valence requirements and give a defect-free interface. These rules are used to analyze epitaxial interfaces of SrTiO[sub 3] on (100)Si. The band offsets are found from the local density of states and it is...

    Ag has been intensively studied to improve the phase transformation of the L10 FePt. The magnetic properties of the FePt thin films with ultrathin Ag top layers prepared by magnetron sputtering have been studied. The crystallopgraphic ordering of the L10 FePt is significantly promoted with Ag...
