Probing Spin Dynamics in an S=1/2 Spin Liquid Candidate: Metal-Organic Framework

Abstract: Quantum Spin Liquids (QSL) are magnetic materials with no long range ordering. We would like to explore the magnetic ground state of a Copper based Metal-Organic Framework (MOF) with suspected quantum spin liquid behaviour. Our magnetization data gives a strong indication of the absence of long range magnetic ordering at low temperature even though strong antiferromagnetic interaction is present in the system, which can be ascertained from Curie-Weiss law.The triangular arrangement of Cu2+ ions along with the magnetic results makes the system extremely interesting from the QSL standpoint. We have also done some preliminary measurements in MuSR beamline which suggests the spins in the system to be dynamic in nature. In this study, we propose to probe the spin dynamics of this MOF at milli Kelvin temperature using dilution refrigerator.
