Journal ArticleDOI
Enhanced electron-electron correlations in nanometric SrRuO 3 epitaxial films
Gervasi Herranz,Benjamín Martínez,Josep Fontcuberta,Florencio Sánchez,C. Ferrater,M.V. García-Cuenca,Maria Varela +6 more
TL;DR: In this article, the authors studied the impact of defect structure associated with a unique growth mode transition on the electronic properties of the films and found that microstructural disorder promotes a shortening of the carrier mean free path.
Journal ArticleDOI
Magnetic characterization of γ-Fe2O3 nanoparticles fabricated by aerosol pyrolysis
TL;DR: In this paper, the magnetic properties of nanoparticles prepared by spray pyrolysis of dilute solutions of Fe(III) and Fe(II) salts have been investigated using both magnetic measurements and Mossbauer spectroscopy.
Journal ArticleDOI
Magnetotransport properties of nanometric La2/3Sr1/3MnO3 granular perovskites
TL;DR: In this paper, the electrical resistivity of granular nanometric La 2/3 Sr 1/3 MnO 3 ceramics is studied as a function of temperature and magnetic field.
Journal ArticleDOI
Magnetic dilution in the strongly frustrated kagome antiferromagnet SrGa12-xCrxO19.
Benjamín Martínez,Felip Sandiumenge,A. Rouco,Amílcar Labarta,Juan Rodriguez-Carvajal,M. Tovar,M. T. Causa,Salvador Galí,Xavier Obradors +8 more
TL;DR: A study of the structural and magnetic characteristics of the strongly frustrated kagome system SrGa 12-x Cr x O 19 (1<×<9) is reported with focus on the effects of the magnetic ion dilution.
Journal ArticleDOI
Diamagnetic Susceptibility and Root Growth Responses to Magnetic Fields in Lens culinaris, Glycine soja, and Triticum aestivum
TL;DR: A simple hypothesis is proposed to relate root growth inhibition with magnetic fields and with the different responses found among species, seasons, and physiological and environmental conditions reported here and in the literature, based on a reduced magnetic force acting on the cell biological substances and on the cellular organelles such as amyloplasts rather than on the cytoplasmic matrix.
