Abstract.

The magnetic properties of a polycrystalline Sr3NiIrO6 sample have been investigated by means of susceptibility and magnetization measurements. On the one hand, it is found that this compound, made of magnetic chains on a triangular lattice, behaves very similarly to Ca3CoRhO6 and Ca3CoIrO6. In particular, at low temperature ( T < T 2 ( = 21 K)), a frozen state, characterized by a very slow spin dynamic, is evidenced. On the other hand, for T 2 < T < T 1 ( = 70 K), this phase exhibits magnetization values, smaller than the expected ones, with a 1/3 plateau reminiscent of the ferrimagnetic state of Ising spins on a triangular lattice. Nonetheless, the absence of saturation in 35 T and the low magnetization values are consistent with an antiferromagnetic intrachain coupling between Ir4+ (S = 1/2) and Ni2+ (S = 1). Sr3NiIrO6 can be viewed as made of antiferromagnetically coupled ferrimagnetic chains on a triangular lattice. On the basis of these results, a magnetic (H, T) phase diagram is proposed.
