WebApr 11, 2024 · The XRD refinement analysis suggested that GGMO and DGMO crystallize in a tetragonal structure. A large magnetic entropy change (ΔS M) of −41.2 J kg −1 K −1 was observed at 1.8 K for GGMO under a magnetic field (ΔH) of 7 T. A moderate ΔS M of −14.1 J kg −1 K −1 was obtained at 4.5 K under a ΔH of 7 T in DGMO. WebWelcome to IST Information Services and Technology
