Possible chiral quantum spin liquid ground state in a hypertrillium lattice antiferromagnet (NH4)(H3O)Ti2 (PO4)3
Abstract: Quantum materials, where frustration, band topology, and spin correlations converge, host a panoply of exotic quantum states such as quantum spin liquids (QSLs), spin ices, and fractional quantum Hall liquids. Systems with strong magnetic frustration are especially promising candidates for realizing the elusive QSL state, characterized by fractionalized excitations and the lack of magnetic long-range order (LRO) at T = 0 K. While significant progress has been made in identifying QSL candidates in 2D kagome and triangular antiferromagnets, their experimental realization in 3D frustrated magnets remains rare. The type of QSLs relies on spin-lattice symmetry. One salient possibility is the chiral spin liquid (CSL), which, despite lacking LRO, breaks both time-reversal and parity symmetries. Here, we focus on a new chiral network of S= 1/2 tetra-trillium lattice of Ti3+ ions. Neither magnetic susceptibility nor specific-heat data show any signature of magnetic ordering down to 1.9 K despite a large Curie-Weiss temperature of - 23 K. We propose a muSR study much below the sub-Kelvin temperatures to unambiguously confirm the chiral QSL state and identify the associated magnetic excitations in this new three-dimensional frustrated magnet in the quantum limit.
