Complex magnetic and dielectric properties of pyrochlore compounds with application potential for quantum technology — •Thomas Herrmannsdörfer and Sumanta Chattopadhyay — Hochfeld-Magnetlabor Dresden (HLD-EMFL), Helmholtz-Zentrum Dresden - Rossendorf (HZDR), Dresden, Germany

We report the magnetic and dielectric properties of selected pyrochlore compounds such as Ho₂Ti₂O₇, Pr₂Hf₂O₇ and Nd₂Hf₂O₇. In this material class, the particular balance of magnetic interactions between rare-earth Ising spins which are located on a network of corner sharing tetrahedra leads to a wide spectrum of frustrated magnetic ground states, such as spin ice and quantum spin ice behavior as well as all-in-all-out antiferromagnetism. We highlight these properties in the context of their potential use for future quantum technological applications.
