Journal ArticleDOI
Evidence for magnetic polarons in the magnetoresistive perovskites
J. M. De Teresa,M. R. Ibarra,Pedro A. Algarabel,Clemens Ritter,Clara Marquina,Javier Blasco,Jose H. Garcia,A. del Moral,Z. Arnold +8 more
TL;DR: In this article, a combination of volume thermal expansion (with and without an applied field), magnetic susceptibility and small-angle neutron scattering measurements was used to detect magnetic polarons above the ferromagnetic ordering temperature, Tc.
Journal ArticleDOI
Double perovskites with ferromagnetism above room temperature
TL;DR: In this article, the structural, magnetic and transport properties of double perovskites with ferromagnetism above room temperature are discussed, and the impact of these materials for spin electronics in the light of their high spin polarization at the Fermi level and metallicity.
Journal ArticleDOI
Nanoparticles as Smart Treatment-delivery Systems in Plants: Assessment of Different Techniques of Microscopy for their Visualization in Plant Tissues
Pablo González-Melendi,Rodrigo Fernández-Pacheco,María José Coronado,Eduardo Corredor,Pilar S. Testillano,M. C. Risueño,Clara Marquina,M. R. Ibarra,M. R. Ibarra,Diego Rubiales,Alejandro Pérez-de-Luque +10 more
TL;DR: In this article, a number of tools for the detection and analysis of core-shell magnetic nanoparticles introduced into plants and their concentration in selected plant tissues by magnetic field gradients are presented.
Journal ArticleDOI
Influence of oxygen content on the structural, magnetotransport, and magnetic properties of LaMnO 3 + δ
Clemens Ritter,M. R. Ibarra,J. M. De Teresa,Pedro A. Algarabel,Clara Marquina,Javier Blasco,Jose H. Garcia,S. B. Oseroff,Sang-Wook Cheong +8 more
TL;DR: A systematic study of the effect of oxygen content on the structural, magnetotransport, and magnetic properties has been undertaken on a series of samples, with the results reported in this paper.
Journal ArticleDOI
Magnetic-field-induced structural phase transition in Gd 5 ( S i 1.8 Ge 2.2 )
L. Morellon,Pedro A. Algarabel,M. R. Ibarra,Javier Blasco,B. García-Landa,Z. Arnold,Franca Albertini +6 more
TL;DR: In this article, the giant magnetocaloric effect was shown to be associated with a field-induced first-order structural transition from a monoclinic (paramagnetic) to a Pnma orthorhombic (ferromagnetic) structure.
