Muon spin rotation and resonant soft X-ray scattering experiments on prototype multiferroics RMn2O5 (R = Y, Sm) are used to demonstrate that the local electric displacements are driven by the spin-current (SC) mechanism. Small local electric displace

A new type of magnetoelectric (ME) effect was discovered in ${\mathrm{Tb}}_{1\ensuremath{-}x}{\mathrm{Gd}}_{x}{\mathrm{Mn}}_{2}{\mathrm{O}}_{5}$ in which Gd ions are substituted into ${\mathrm{TbMn}}_{2}{\mathrm{O}}_{5}$. The substitution of Gd ions

Fine grained samples with a nominal composition of Bi 0.5 Sb 1.5 Te x (x = 3.0 to 3.4) were prepared by mechanical alloying (MA). Average grain sizes were found to range from 1.0 to 2.1 μm. Tellurium precipitation at x = 3.1 was observed by scanning

N-type tellurium doped ZnSb was prepared by direct melting at 923 K after which it was quenched in water within an evacuated quartz ampoule. All the ingots were heat treated at 723 K for 100 h. The resultant samples were characterized by X-ray diffra

We developed a porous SiC/C composite by oxidizing a SiC/C composite made from a mixed powder of wood charcoal and SiO2 (32-45 mu m) by pulse current sintering at 1600 and 1800 degrees C under a N-2 atmosphere. The microstructures of the porous SiC/C
