报告摘要：The spin-chain systems A3MM’O6 (A = alkaline-earth metal, M/M’ = transition metals) have reduced dimensionality in the presence of geometrical frustration, thus show strong spin anisotropy and spin-orbital coupling on the magnetism. In this talk, I will present our recent studies on the magnetism of Sr3NiIrO6, Sr3ZnIrO6 and Sr3NiPtO6 using neutron scattering and μSR measurements. We will also compare the magnetic excitations among them and discuss the nature of spin-liquid ground state in Sr3NiPtO6 .
Dr Devashibhai Adroja is a senior scientist at the ISIS facility, Rutherford Appleton Laboratory, UK and is responsible for the MERLIN spectrometer and he is also a visiting professor at Johannesburg University, South Africa. His research programme is focused on strongly correlated electron systems with more than 24 years of experience in neutron scattering and muon spin rotation technique. Dr Adroja obtained his Ph.D. from IIT Bombay (in 1991), India, and then worked as a research fellow at Southampton, Hiroshima (JSPS fellowship 1997), St Andrews universities before joining ISIS in 1999. Since 2001, he work at ISIS as an instrument scientist in Excitations group, then from 2007 to present, he become a Senior Scientist at ISIS. He was the pioneer in discovering the Kondo insulator CeRhS, and the related materials Ce(NiCo)Sn and CePdSb. Recently he has made significant contributions to the field of spin and charge gap formation in strongly correlated electron systems and published two review papers on this topic. He has published over 290 papers.
