Dynamic effects in one-dimensional A′3ABO6

Low-dimensional transition metal oxides provide excellent model systems to study magnetic properties induced by the interplay between low-dimensionality character and frustration. In this work, we study polycrystalline Sr3NiIrO6 and Ca3CoIrO6 compounds which exhibit at low temperatures a frozen state with notable dynamic effects that can be attributed to the low-dimensionality character. These dynamic effects are probed by AC susceptibility measurements.
