Absence of static magnetic order in lightly-doped Ti1-xScxOCl down to 1.7 K

Impurity-induced magnetic order has been observed in many quasi-1D systems including doped variants of the spin-Peierls system CuGeO3. TiOCl is another quasi-1D quantum magnet with a spin-Peierls ground state, and the magnetic Ti sites of this system can be doped with nonmagnetic Sc. To investigate the role of nonmagnetic impurities in this system, we have performed both zero-field and longitudinal-field μSR experiments on polycrystalline …
