Low Temperature Surface Spin-Glass Transition in γ - Fe 2 O 3 Nanoparticles

Benjamín Martínez, +4 more
- 05 Jan 1998 - 
TL;DR: In this paper, a spin-glass-like transition was found in magnetic nanoparticles, with a very high surface to volume ratio, exhibiting both strong exchange anisotropy and magnetic training effect.
Journal ArticleDOI

Strong isotropic flux pinning in solution-derived YBa2Cu3O7-x nanocomposite superconductor films.

J. Gutierrez, +10 more
- 01 May 2007 - 
TL;DR: Angle-dependent critical-current measurements demonstrate that a strong and isotropic flux-pinning mechanism is extremely effective at high temperatures and high magnetic fields leading to high-temperature superconductors with record values of pinning force.
Journal ArticleDOI

Colossal magnetoresistance of ferromagnetic manganites: Structural tuning and mechanisms.

Josep Fontcuberta, +5 more
- 12 Feb 1996 - 
TL;DR: The amplitude $\ensuremath{\rho}(T,H)$ and temperature ${T}_{M}$ and CMR are found to be controlled by the radius of the lanthanide $({L}^{3+})$ which modifies the bending of the Mn-O-Mn bond.
Journal ArticleDOI

Coated conductors for power applications: materials challenges

Xavier Obradors, +1 more
- 18 Mar 2014 - 
TL;DR: The scientific and technological scope where CCs have been raised as a complex technology product is summarized and it is shown that there exists still much room for performance improvement.
Journal ArticleDOI

Nanoscale strain-induced pair suppression as a vortex-pinning mechanism in high-temperature superconductors

Anna Llordes, +22 more
- 01 Apr 2012 - 
TL;DR: A new vortex- pinning mechanism based on the bond-contraction pairing model is suggested, where pair formation is quenched under tensile strain, forming new and effective core-pinning regions.
