Studies on Novel Yb-based Candidate Triangular Quantum Antiferromagnets: Ba3YbB3O9 and Ba3YbB9O18

Abstract

Yb-based triangular magnets have recently attracted attention as promising candidates to explore frustrated quantum magnetism. However, some candidates have turned out to have significant amounts of site disorder, which significantly affects the low-temperature magnetic behavior. To overcome this issue, Yb-based frustrated systems without structural disorder are required. In this paper, we report physical properties of two Yb-based triangular magnets Ba3YbB3O9 and Ba3YbB9O18, without structural disorder. Via magnetic susceptibility, magnetization, and muon spin rotation measurements, we verified that both Ba3YbB3O9 and, particularly studied for the first time, Ba3YbB9O18 do not show long range magnetic order or glass-like spin freezing down to 0.28 K, but show typical paramagnetic behavior.
