Raman Spectroscopy Group and Users Center

The Raman spectroscopy group is focused on studies of charge and spin ordered ground states in strongly correlated electron systems. Our current aim is to investigate them with Raman spectroscopy to find general behavior for materials of different chemical origin (both organic and inorganic).

Congratulation to Jesse for receiving an ICAM QuantEmX award. This award will support his visit to ISSP, University of Tokyo, laboratory of our long term collaborator  Prof. Minoru Yamashita.  Jesse will study charge ordering transition in organic Mott insulators under strain using resistivity and magnetic susceptibility. Jesse will join Natalia, who will be a Visiting Professor at ISSP for two month this summer. 

Our paper on the energy separation of the lattice modes and vibrational modes of linkers in magnetic metal-organic frameworks Me-BIF (Me=Co,Ni,Cu) is published in The Journal of Chemical Physics:   Raman scattering spectra of boron imidazolate frameworks containing different magnetic ions 

Our paper with the group of Natalia Perkins demonstrating quantum spin ice fluctuations of Nd moments in Nd2Ir2O2 is now on arxiv: Ramification of complex magnetism in Nd2Ir2O7observed by Raman scattering spectroscopy
