Role of defects in determining the magnetic ground state of ytterbium titanate

Role of defects in determining the magnetic ground state of ytterbium titanate

Exploring the role of structural defect is essential to understand the exotic quantum spin phenoma in rare earth pyrochlores. Here the authors show oxygen vacancies can stabilise the spin liquid phase and reveal the ferromagnetic ground state when oxygen vacancies are eliminated in Yb2Ti2O7.
