Here, we present muon spin relaxation (μSR) measurements of the extended kagome systems YBaCo₄O_7+δ (δ = 0,0.1), comprising two interpenetrating kagome sublattice of Co(I)³⁺ (S = 3/2) and a triangle sublattice of Co(II)²⁺ (S = 2). The zero- and longitudinal-field μ SR spectra of the stoichiometric compound YBaCo₄O₇ unveil that the triangular subsystem orders at TN = 101 K. In contrast, the muon spin relaxation rate pertaining to the kagome subsystem shows persistent spin dynamics down to T = 20 K and then a sublinear decrease λ(T ) ~ T^0.66(5) on cooling towards T = 4 K. In addition, the introduction of interstitial oxygen (δ = 0.1) is found to drastically affect the magnetism. For the fast-cooling experiment (>10 K/min), YBaCo₄O_7.1 enters a regime characterized by persistent spin dynamics below 90 K. For the slow-cooling experiment (1 K/min), evidence is obtained for the phase separation into interstitial oxygen-poor and oxygen-rich regions with distinct correlation times. The observed temperature, cooling rate, and oxygen content dependencies of spin dynamics are discussed in terms of a broad range of spin-spin correlation times, relying on a different degree of frustration between the kagome and triangle sublattices as well as of oxygen migration.
