dc.description.abstract | We report the magnetic susceptibility, specific heat, and muon spin relaxation results of the 5d1 double perovskite Ba2YWO6. The dc magnetic susceptibility shows two distinct Curie-Weiss regimes and a sub-Curie-Weiss increase T-n with n=0.75(1) for T=3-100 K, alluding to the presence of random magnetism. The ac magnetic susceptibility reveals a spin freezing at Tf∼0.3 K with the activation energy of Δ/kB=27.6 K. The specific heat data exhibit the pseudogap behavior at 25 K and the subsequent power-law dependence with decreasing temperature, indicating the gradual spin freezing with the quenching of orbital fluctuations. However, the muon spin relaxation data display only a weak muon spin depolarization with lacking long-range magnetic ordering down to 26 mK. Taken together, our results suggest that Ba2YWO6 is the proximate realization of a random spin-orbit dimer state. © 2021 American Physical Society. | - |
