- Аннотация: The decisive role of magnetic anisotropy even in systems with small anisotropy is illustrated for the honeycomb layered antiferromagnets A3Ni2SbO6 with A=Li and Na. Both systems evolve long range magnetic order below TN =14 and 16.5 K, respectively. The magnetic phase diagrams obtained from static magnetisation studies up to 15 T imply competing antiferromagnetic phases and a tricritical point at TN. The phase boundaries are visible in the dynamic response of the antiferromagnetic resonance modes, too, which investigation by means of high frequency/high field electron spin resonance enables precise determination of magnetic anisotropy. The anisotropy gap amounts to Δ = 360 ± 2 GHz in Na3Ni2SbO6 while in Li3Ni2SbO6 orthorhombicity is associated with Δ = 198 ± 4 and 218 ± 4 GHz. Above TN, the data imply short-range antiferromagnetic order up to at least 80 K. The data suggest a crucial role of anisotropy for selecting the actual spin structure at B = 0 T.
