An experiment obtains a spin liquid state by squeezing a magnetic crystal

Published Mon, Jun 15, 2020
A group at the Advanced Photon Source (APS) of the Argonne National Laboratory (USA) has obtained a state of matter closely resembling a quantum spin liquid. Such a state is characterized by a “frustration” of the electron spins – the situation in which the electrons are not able...
