A paper on the Ising quantum spin liquid on a triangular lattice published in Nature Materials

The Ising triangular-lattice antiferromagnet neodymium heptatantalate as a quantum spin liquid candidate

Nature Materials (2021)

In collaboration with researchers from the Institute of Mathematics, Physics and Mechanics and research institutions from India, the UK, France and the US, we discovered the first realization of a quantum spin liquid on a triangular spin lattice with dominant Ising antiferromagntic exchange interaction. An extensive experimental study was conducted, showing the absence of magnetic ordering and proving the existence of Ising-type spin correlations in neodymium heptatantalate NdTa7O19 at temperatures of only a few tens of millikelvins. The discovery of the Ising spin liquid introduces a new type of this enigmatic quantum entangled state of matter that remains dynamical down to the lowest temperatures. These results are published in the paper entitled The Ising triangular-lattice antiferromagnet neodymium heptatantalate as a quantum spin liquid candidate in the esteemed Nature Materials journal.
