We are a group of researchers who address today's challenges to understand the complex structure-property relation of oxide materials. By growing oxide compounds layer by layer, i.e., ultrathin epitaxial films or superlattices, we aim to tune their structural and electronic properties further and even stabilize new phases and access novel functionalities.

We investigate thin films of the ferromagnetic and insulating double perovskite Nd2NiMnO6 grown by magnetron sputtering. For 30-unit cell films, we find a bulk-like Curie temperature TC of approximately 200 K independent of epitaxial strain. In samples grown on SrTiO3 substrates, ferromagnetism is conserved down to 3 unit cells. A detailed synchrotron study allows us to separate the magnetic components into a robust ferromagnetic Ni/Mn sublattice and a paramagnetic Nd sublattice.

Alba´s experiments

Member of the groups in the Alba synchrotron.


We have been measuring at ALBA synchrotron, close to Barcelona. The intense and high-resolved synchrotron light has been used to carry out multiple x-rays magnetic linear (XMLD) and circular (XMCD) dichroism measurements on a set of SrCrO3 (SCO) thin film samples. Exciting results!

IWOE 29, South Korea

Marie, Simon, and Marta at an oxidos congress in south korea

Marie, Simon, and Marta attended the 29th International Workshop on Oxide Electronics in the exciting city of Busan in South Korea, where Marie presented her works entitled "Exchange bias effect in double perovskite/perovskite heterostructures" and Simon showed his results on "Metal-to-insulator transition in antiferromagnetic SrCrO3 thin films".

Congratulations Jonathan!!!

A group´s picture after the successful Ph.D. defense of Jonathan Spring. Among other scientist, Prof. Marta Gibert is in the picture, and of course Jonathan Spring

We are very proud of the successful defense of the Ph.D. of Jonathan Spring, who was responsible for thoroughly investigating the growth of multilayer perovskites under the supervision of Marta Gibert. 

Top-Layer Engineering

An atomically resolved image of a double perovskite and its representation is observed

The introduction of a top electron-acceptor layer (i.e. LaNiO3) redistributes the electron excess and restores the ferromagnetic properties of the ultrathin of the ultrathin double-perovskite insulating ferromagnetic La2NiMnO6 (LNMO) thin films. Such a strategy can be extended to other interfaces and provides an advanced approach to fine-tune the electronic features of complex multilayered heterostructures.

New sputtering chamber

the CAD-drawing of a sputtering chamber is observed

Our new sputtering system chamber has already been designed and is being built in the workshop of Vakuum Praha in the Czech Republic. The vacuum chamber is based on a cylindrical stainless steel tube with multiple flanges connected to specific elements. In particular, more than eight flanges pointing directly to the sample allow us multiple access options directly to our sample during the growing process.
