Phys.org April 18, 2023 For two decades, it was believed that a possible quantum spin liquid was discovered in a synthetically produced material. In this case, it would not follow the laws of classical physics even on a macroscopic level, but rather those of the quantum world. An international team of researchers (Austria, Spain) has shown that the promising material, κ-(BEDT-TTF)2Cu2(CN)3, is not the predicted quantum spin liquid, but a material that can be described using known concepts. They were able to precisely map the spin-gapped phase through the Mott transition by ultrahigh-resolution strain tuning. Through transport experiments they revealed […]

Physicists find first possible 3-D quantum spin liquid
Phys.org July 15, 2019 A quantum spin liquid is a state of matter where unpaired electrons’ spins, although entangled, do not show magnetic order even at the zero temperature. An international team of researchers (USA – Rice University, UC San Diego, Oak Ridge National Laboratory, Rutgers University, industry, UK, Switzerland, South Korea, University of Hong Kong) used thermodynamic, muon spin relaxation and neutron scattering experiments on single crystals of Ce2Zr2O7 to demonstrate the absence of magnetic ordering 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 […]
