Electrospinning has been used to fabricate ferromagnetic Ni0.47Fe0.53 nanofiber mats that were composed of individual, orientated Ni0.47Fe0.53 nanofibers. The key steps were processing a polyvinylpyrrolidone nanofiber template containing ferric nitra

The narrow band gap semiconductors Bi2Te3 and Sb2Te3 are well known for their room temperature thermoelectric performance. Recently, they were shown to serve as model systems of three-dimensional topological insulators with a bulk band gap and very r

Air annealing has been found to increase both T c and J c of FeSe1-xTex single crystals. However, there are indications that this effect might be limited to the surface of the crystals. In this work, we report on the changes in the surface structure

Very recently, nuclear magnetic resonance (NMR) of 209Bi has been shown to provide quantitative access to the bulk band inversion in the topological insulator Bi2Se3 and detected a highly unusual f...

Photoluminescence (PL) features arising from intraconfigurational 4f – 4f transitions and also O2− → Ln3+ charge transfer (CT) where Ln3+ = Yb3+, Sm3+ or Eu3+ are observed for Ln-doped NaMgF3 with oxygen impurities. The peak CT stimulation ener

We report the use of nanoparticle (NP) magnetite, Fe3O4, in magnetostrictive-piezoelectric composites in trilayer laminate and single layer form. The magnetoelectric (ME) effect in both structures is highly anisotropic and linear up to 9 kOe. A trila

Room temperature implantation of 30 keV Co ions into an amorphous carbon film with a high fluence of 1.2 × 1017 Co/cm2 results in formation of magnetic nanostructures displaying multiple magnetic phases. Cross-sectional TEM images show formation of
