Magnetically frustrated coordination polymers as Quantum Spin Liquid candidates

Magnetic coordination polymers have emerged as potential candidates to behave as Quantum Spin Liquids (QSLs). The QSL is a state of matter proposed by Anderson in 1973, where, due to magnetic frustration, the spins fluctuate in a liquid-like state even at zero temperature. In this proposal we explore three magnetically frustrated organic-inorganic materials in the form of coordination polymer oxalates with honeycomb type structures. Two of these are bimetallic honeycomb lattice compounds containing Ru(III)/Ru(II) and Ru(III)/Cu(II) that are strong candidates to give Kitaev QSLs due to significant spin-orbit coupling . The third is a Co(II) compound with a hyperhoneycomb structure that is also a highly frustrated QSL candidate. Low temperature muSR measurements will be used to test and evaluate the properties of these candidate QSL materials.
