Pyrochlores with SOC

Full project name:

Electron and magnetic properties of R2T2O7 pyrochlores with strong spin-orbit coupling

Project Details

The aim of the project is to contribute to the progressively developing research on the rare-earth pyrochlores R2Ir2O7. The investigation of magnetic structures, magnetic excitations and conductivity, as a result of the antiferromagnetically coupled moments on the geometrically frustrated lattice and interplay between spin-orbit coupling and electron correlations in these compounds, forms the main part of the project. The main focus, besides the macroscopic properties study, is dedicated to a better understanding of the microscopic mechanisms leading to the observed phenomena and their evolution with the rare-earth element. Non-trivial samples synthesis and characterization; magnetization, ac-susceptibility or specific heat measurements; will be corroborated by synchrotron radiation, muon and neutron scattering experiments. Simultaneously, the project aims to establish the problematics of rare-earth pyrochlore oxides within the current fundamental science research on the ground of Charles University.
