Quantum Design‘s ACDR option – publication in Nature Physics

From the abstract of Bin Gao et. al. nature article using the AC susceptibility option for the dilution refrigerator of the PPMS from Quantum Design: “A quantum spin liquid is a state of matter where unpaired electrons’ spins, although entangled, do not show magnetic order even at zero Kelvin temperature. The realization of a quantum spin liquid is a long-sought goal in condensed-matter physics. Here, we use thermodynamic, myon spin relaxation and neutron scattering experiments on single crystals of Ce2Zr2O7, a compound isostructural to Ce2Sn2O7, to demonstrate the absence of magnetic order and the presence of a spin excitation continuum at 35 mK. With no evidence of oxygen deficiency and magnetic/non-magnetic ion disorder seen by neutron diffraction and diffuse scattering measurements, Ce2Zr2O7 may be a three-dimensional pyrochlore lattice quantum spin liquid material with minimum magnetic and non-magnetic chemical disorder.”
