    • Relation of the average interaction field with the coercive and interaction field distributions in First order reversal curve diagrams of nanowire arrays 

      Velázquez Galván, Yenni Guadalupe; Lobo Guerrero, Azdrubal; Martínez Huerta, Juan Manuel; Araujo Palomo, Elsie Evelyn; Tabasum, Muhammad Ramzan; Nysten, Bernard; Piraux, Luc; Encinas Oropesa, Armando (Nature Publishing Group, 2020)
      "First-order reversal curve diagrams, or FORC diagrams, have been studied to determine if the widths of their distributions along the interaction and coercivity axes can be related to the mean-field magnetization dependent ...

    • Structure and photocatalytic activity of maleic anhydride-functionalized TiO2 nanoparticles by a simple method 

      Hernández Del Castillo, Pável César; Robles Manuel, Saùl; Ruiz, Facundo; Rodríguez González, Vicente (BMC, 2022)
      "Titanium dioxide (TiO2) nanoparticles were functionalized with maleic anhydride (MA). The extension of adsorbed MA on the TiO2 was evaluated by ultrasonic and magnetic stirring. Total Organic Carbon and Thermogravimetric ...

    • Superlinear photoluminescence by ultrafast laser pulses in dielectric matrices with metal nanoclusters 

      Bornacelli, J.; Torres Torres, Carlos; Silva Pereyra, Héctor Gabriel; Labrada Delgado, Gladis Judith; Crespo Sosa, Alejandro; Cheang Wong, Juan Carlos; Oliver y Gutiérrez, Alicia María (Nature Publishing Group, 2019)
      "An intense photoluminescence emission was observed from noble metal nanoclusters (Pt, Ag or Au) embedded in sapphire plates, nucleated by MeV ion-implantation and assisted by an annealing process. In particular, the ...

    • Superparamagnetic state in La0.7Sr0.3MnO3 thin films obtained by rf-sputtering 

      Ramírez Camacho, Mayra Cecilia; Sánchez Valdés, Cesar Fidel; Curiel Álvarez, Mario; Sánchez Llamazares, José Luis; Siqueiros, Jesús M.; Raymond Herrera, Oscar (Nature Publishing Group, 2020)
      "A novel superparamagnetic state has been observed in high quality La0.7Sr0.3MnO3 (LSMO) thin films directly grown by rf-sputtering on SiOx/Si(100) substrates. The films are nanostructured without grain boundaries, constituted ...

    • Synthesis, characterization and magnetic properties of defective nitrogen-doped multiwall carbon nanotubes encapsulating ferromagnetic nanoparticles
