Superconductivity in LaNiPO is disrupted by small $(\ensuremath{\sim}5%)$ amounts of nonstoichiometry on the lanthanum site, even though the electronic contribution to the heat capacity increases with increasing nonstoichiometry. All samples also exhibit specific-heat anomalies consistent with the presence of ferromag…

Synchrotron X-ray, neutron powder diffraction, magnetic susceptibility, and electrical resistance measurements were used to investigate the Nd 1− x Ca x FeAsO series. The solubility of calcium is limited to 0 ≤ x ≤ 0.05. Within this interval, the iron arsenide layer contracts linearly in agreement with the hole doping…

Abstract Using conventional methods to synthesize magnetic nanoparticles (NPs) with uniform size is a challenging task. Moreover, the degradation of magnetic NPs is an obstacle to practical applications. The fabrication of silica‐shielded magnetite NPs on carbon nitride nanotubes (CNNTs) provides a possible route to o…

Deposition of submonolayer coverages of 3,4,9,10-perylenetetracarboxylic diimide onto NaCl(001) results in the bimodal growth of coexisting square and needle-shaped islands. The epitaxy of each island type was determined from molecular and atomic resolution noncontact atomic force microscopy images. Postdeposition, th…
