In kagome metals, the chiral current order parameter η with time-reversal-symmetry-breaking is the source of various exotic electronic states, while the method of controlling the current order and its interplay with the star-of-David bond order ϕ are still unsolved. Here, we reveal that tiny uniform orbital magnetization M orb [ η , ϕ ] is induced by the chiral current order, and its magnitude is prominently enlarged under the presence of the bond order. Importantly, we derive the magnetic-field ( h z )-induced Ginzburg–Landau (GL) free energy expression Δ F [ h z , η , ϕ ] ∝ − h z M orb [ η ,</mm
