Abstract
AbstractThe magnetic anisotropy of the quantum-critical spin-chain system YbAlO$$_3$$
3
is studied in detail in its paramagnetic phase by means of electron spin resonance. We find an uniaxial g factor anisotropy with $$g_\parallel =7.01$$
g
‖
=
7.01
and $$g_\perp = 0.47$$
g
⊥
=
0.47
. The existence of two distinct magnetic Yb sites explains the resonance spectra well.
