An investigation of the effects ofB-site cationic disorder on the magnetic ground state of the quantum spin ice candidate Yb2Ti2O7

DOI

For over 50 years, the true magnetic ground state of Yb2Ti2O7 (YTO) still remains a mystery. The Cp of YTO exhibits a sharp feature, originally suspected to be the formation of an LRO. Neutron scattering, in combination with both Mössbauer and µSR demonstrated that YTO represents a unique case where a frustrated system does not assume an LRO after a sharp feature in Cp but experiences a transition into a persistently fluctuating state. To freeze such fluctuations, Hodges et al. investigated the disordered Yb2GaSbO7 (YGSO). The disorder was believed to introduce exchange disorder to overwhelm the frustration that led to the persistent dynamics in YTO. Instead, Hodges et al. demonstrated that the disorder in YGSO did not overwhelm the frustration, instead it reinforced the persistent dynamics. Despite the identification of a persistent fluctuating state, there have been no published neutron scattering studies to confirm the absence of a static LRO magnetic state. Our recent measurements on the FIE-TAX HB-1A revealed evidence for weak spin liquid correlations. We propose to use 7 days on D7 to isolate and characterise the spin liquid correlations that constitute YGSO's ground state.
