English By muon spin rotation we investigated the magnetic properties of a series of highly Na-doped Na<sub><i>x</i></sub>CoO₂ single crystals with 0.78(1) ≼ x ≼ 0.97(1). Our data provide evidence for an intrinsically inhomogeneous magnetic state which can be described in terms of hole-doping (Na vacancy)-induced magnetic clusters that percolate at 1−<i>x</i>≳0.04 until they yield a bulk magnetic...
