The novel oxides group is an interdisciplinary, experimental research group engaged in the study of fundamental aspects of condensed matter physics and materials science. We are particularly interested in explore the diverse behavior of functional complex oxide materials such as high-temperature superconductors, manganites, cobaltites, ruthenates, etc. Structurally and chemically complex oxides are one of the most promising classes of materials to realize new phenomena with direct technological implications. Indeed, these fascinating class of materials have been already used in fuel cells, batteries, and electronics due to their multifunctional electronic, magnetic, and structural properties. In addition to synthesis, the researchers in the group utilize a range of characterization techniques including structural, electrical, optical, and magnetic measurements performed using experimental infrastructure available both at the National University of Colombia as well as in different laboratories in the country and abroad, which effectively collaborate with our group.

Complex oxides are suitable systems for achieving novel materials and devices. Although a great deal of knowledge has been accumulated in the last decades, there is a lot left to learn. Thus, it is true that important steps have been made in the fundamental understanding of these materials and the origin of emergent properties within them, such as high-temperature superconductivity, metal-insulator transitions, and colossal magnetoresistance. Nevertheless, it is also true that the complexity of these materials, stemming from the close interplay between charge, spin and orbit, requires that new strategies to control emergent properties and to engineer novel, technologically relevant materials and devices should be designed. In the recent years, there has been an increased number the students interested in the subject of condensed matter physics and materials sciences. This trend is seen both in the science and engineering faculties. Hence, the advanced oxides group (AOG) strive to support and foster the interdisciplinary education and research on advanced materials in science and engineering. The AOG’s educational goals include undergraduate, graduate and postdoctoral students.

The focus of the AOG’s research is investigating and perfecting the properties of oxide materials with the purpose of contributing to address fundamental questions arising in condensed mater physics and exploring potential applications of these materials in a wide range of technologies. In doing so, we are advancing the study of new materials, from improving the synthesis methods to reinforce the contact to strong research groups both in the country and abroad. In short, our focus on oxides is due to the tremendous promise that these materials hold for addressing fundamental problems in condensed matter physics and technological applications..

The AOG is an Interdisciplinary research group. The group tries to bring together students and researchers with diverse expertise. The spectrum of scientific interest of the AOG spans Science and Engineering. Thus, the AOG works collaboratively with researchers in other fields, including physics, applied physics, chemistry, electrical engineering and Materials Science. In this way, complex, interdisciplinary challenges in materials research have been addressed. The activities of the AOG are supported by a variety of national and international partnerships, which has allowed us to face complex and multi-faceted projects. As we strive to develop new knowledge and/or technologies, we also endeavor to improve the efficiencies of existing infrastructure in our laboratory. Here, the contact to international companies supplybg special equipement is of central importance. Finally, although financial support of the scientific research can be a limiting factor for many groups, we believe that in our case, the limits are the essential properties of the elements and their compounds, and the laws of physics.
