Spin dynamics in hafnium-doped holmium titanate pyrochlore.
Following a theoretical study, we propose to investigate possible disorder-induced Quantum Spin Liquids. A possible route to tune such disorder is to control the density of Frenkel pair defects in an initially classical pyrochlore spin ice. This can be achieved by admixing quadrivalent cations at the pyrochlore B site. In this spirit, a series of non-Kramers rare-earth pyrochlore was synthesized and characterized using XRD, NPD and magnetic susceptibility. Experimental observations corroborate the persistence of spin ice correlations along with strengthened fluctuations due to disorder-induced transverse fields. A change in the spin dynamics is thus expected, compared to the classical spin ice. This experiment aims at using neutron spin echo spectroscopy on Ho2(Ti0.9Hf0.1)2O7 and compare its dynamics with that of the classical system Ho2Ti2O7.
