Here, we present a thorough study of doping dependent magnetic hysteresis and relaxation characteristics in single crystals of (Ba_1-xK_x) Fe₂As₂ (0.18 ≤ x ≤ 1). The critical current density J_c reaches maximum in the underdoped sample x = 0.26 and then decreases in the optimally doped and overdoped samples. Meanwhile, the magnetic relaxation rate S rapidly increases and the flux creep activation barrier U₀ sharply decreases in the overdoped sample x = 0.70. These results suggest that vortex pinning is very strong in the underdoped regime, but it is greatly reduced in the optimally doped and overdoped regime. Transmission electron microscope (TEM) measurements reveal the existence of dislocations and inclusions in all three studied samples x = 0.38, 0.46, and 0.65. An investigation of the paramagnetic Meissner effect (PME) suggests that spatial variations in T_c become small in the samples x = 0.43 and 0.46, slightly above the optimal doping levels. Our results support that two types of pinning sources dominate the (Ba_1-xK_x) Fe₂As₂ crystals: (i) strong δl pinning, which results from the fluctuations in the mean free path l and δT_c pinning from the spatial variations in T_c in the underdoped regime, and (ii) weak δT_c pinning in the optimally doped and overdoped regime.
