Abstract:
The magnetic anisotropy of the quantum-critical spin-chain system YbAlO$$_3$$is studied in detail in its paramagnetic phase by means of electron spin resonance. We find an uniaxial g factor anisotropy with $$g_\parallel =7.01$$and $$g_\perp = 0.47$$. The existence of two distinct magnetic Yb sites explains the resonance spectra well.
