II ALBA User's Meeting
Oral presentations
The widely varying magnetic and electrical properties of spinel ferrites make them promising materials for spintronics applications. In particular, the magnetite is electrically conducting with <111> as easy axis, while cobalt ferrite is an insulating hard ferrimagnet with a magnetocrystalline anisotropy over an order of magnitude larger than that of the magnetite and with <100> easy axis [1]....

II ALBA User's Meeting
Oral presentations
The structure of heterogeneous catalysts is dynamic and both their surface structure and composition may be modified when the gaseous conditions change in order to adapt their electronic properties and geometry to the new atmosphere. Some structures and active phases only exist under reaction conditions and can differ from those identified under UHV conditions [1]. Thus, the study of catalytic...

Oral presentations
The spin state of Co ions is a key degree of freedom in many *Ln*1-x*A*xCoO3 (*Ln*: lanthanide, *A*:alkaline-earth) oxides with remarkable physical properties. In (Pr,*Ln*1-x)CaxCoO3 cobaltites near half-doped (x≈0.5), Co3+ spin-state sharp changes induce a first-order Pr3+ to Pr4+ valence shift...
