Description
In the search for Quantum Spin Liquid (QSL) phases, Rare-Earth pyrochlores are of interest to stabilize Spin Ice states. In QSL candidates, magnetic neutron scattering is a well-established probe for studying magnetic order and interactions. However, in rare-earth elements, degrees of freedom can include magnetic and electric multipoles, which are elusive in scattering experiments. Then, bulk techniques like specific heat and magnetostriction, especially at ultra-low temperatures (ULTs), are crucial to detect phase transitions “hidden” in scattering experiments. We present magnetostriction measurements on Quantum Spin Ice candidates and the development of a heat capacity probe at ULTs.
