Cinthia Piamonteze has spent most of her carrier performing research on synchrotron facilities, with expertise on x-ray absorption spectroscopy. She completed her PhD in physics at University of Campinas, Brazil, working at the Brazilian Synchrotron Light Source (LNLS). Her PhD work was on nickelate systems, using soft and hard x-ray absorption spectroscopy to probe how the electronic and structural properties of these systems change across their metal to insulator transition. During her PhD project she was heavily involved in multiplet calculations for the simulation of x-ray absorption spectra.
After completing her PhD, she moved to the Advanced Light Source at Lawrence Berkeley National Laboratory (LBNL) in Berkeley, California for her post-doctoral work. Initially she investigated metalloproteins making use of x-ray absorption spectroscopy to investigate the valence and site symmetry of metal ions inside active sites in enzymes, for example, those responsible for CO oxidation or reduction of N2 to ammonia. Still at ALS, she turned her scientific focus to complex oxides making wide use of x-ray magnetic circular dichroism.
In 2007 she joined the Paul Scherrer Institute, where she was the scientist responsible for the construction and commissioning of the X-Treme beamline. She took an active role in the beamline optics calculation, planning of the construction and budget, as well as the end-station acceptance tests.
Currently, she is one of the staff scientists in the X-Treme beamline and develops her own scientific projects besides giving expert support to scientific groups coming to the beamline. Her scientific interests include the discovery and investigation of novel properties at the interface between complex oxides in high quality heterostructures and the control of magnetism by electric fields. She is a member of beamtime proposal advisory committees and a reviewer for several scientific journals.
Cinthia Piamonteze’s main responsibilities are the technical development of the X-Treme beamline as well as scientific and technical support of external users. She is also a member of different committees inside PSI and international ones. She is the chair for the organization of the PSI school for master students, the PSI delegate for the experiment environment workgroup within LEAPS. Since 2010 she is in the PSI committee for equal opportunities, which is responsible for proposing projects to support work/life balance, balanced gender representation in natural sciences at PSI, as well as to spark the interest of the young generation in natural sciences. Since 2019 she is a member of the research committee at PSI (Forschungskommission - FoKo), which, among other tasks, is responsible for reviewing scientific proposals that require PSI funding.
Cinthia Piamonteze’s research interest involves the creation and investigation of new magnetic properties at the interface between complex oxides, in high quality heterostructures. In such heterostructures the interface can at times be the key responsible for the properties observed. Heterostructures can also help to disentangle charge, orbital and magnetic degrees of freedom by manipulating one of them through the proximity with another system. Examples of such systems of current interest are heterostructures involving nickelates/manganites or ruthenates/manganites. On the palette of heterostructures studied, are also artificial multiferroic systems where a ferromagnet and a ferroelectric are coupled through an interface. In this case, the goal is to investigate the different mechanisms involved on the control of magnetism by an electric field. The key techniques used are x-ray magnetic circular dichroism and x-ray linear dichroism. The use of multiplet calculations to simulate x-ray absorption spectra follows closely her scientific projects.
