The ground state of the simple Heisenberg nearest-neighbor quantum kagomeantiferromagnetic model is a magnetically disordered spin liquid, yet variousperturbations may lead to fundamentally different states. Here we disclose theorigin of magnetic ordering in the structurally-perfect kagome materialYCu$_3$(OH)$_6$Cl$_3$, which is free of the widespread impurity problem. {\itAb-initio} calculations and modeling of its magnetic susceptibility revealthat, similar to the archetypal case of herbertsmithite, the nearest-neighborexchange is by far the dominant isotropic interaction. Dzyaloshinskii-Moriya(DM) magnetic anisotropy deduced from electron spin resonance and specific-heatmeasurements is, however, significantly larger than in herbertsmithite. Byenhancing spin correlations within kagome planes, this anisotropy is essentialfor magnetic ordering. Our study isolates the effect of DM anisotropy fromother perturbations and unambiguously confirms the theoretical phase diagram.
