Quantum Oscillations in PrNi<sub>2</sub>Cd<sub>20</sub> and PrPd<sub>2</sub>Cd<sub>20 </sub>Compounds

ORAL

Abstract

Our group recently discovered a variation of the RT2X20 (R is a rare earth element, T a transition metal) compounds with X = Cd that contain both d- and f- electron ions that can generate correlated electron behavior which may act together to produce novel emergent quantum phenomena. Magnetic measurements on PrNi2Cd20 and PrPd2Cd20 do not show signs of magnetic order down to 2 K and these compounds appear to have complex Fermi surfaces. To probe the Fermi surface and test relevant theories, we have grown single crystals of PrNi2Cd20 and PrPd2Cd20 and have measured Shubnikov de Haas quantum oscillations using the Proximity Detector Oscillator (PDO) method under high magnetic fields up to 60 T at low temperatures of around 1.5 K. Samples were mounted on a rotation stage, allowing the field to be applied at many different orientations with respect to the crystal axis.
