The external field dependence of the hyperfine field at La-site has been studied on La{sub 2{minus}x}Sr{sub x}CuO{sub 4}(x = 0.115) and La{sub 2{minus}x}Ba{sub x}CuO{sub 4}(x = 0.125), where the magnetic ordering in Cu-3d spins exists at low temperature. In La{sub 1.885}Sr{sub 0.115}CuO{sub 4}, a significant decrease in the resonance line width was observed above a field of H{sub c} {approx} 7.5T, which is the direct evidence of the spin-flop in the canted-spin system with Dzyaloshinski-Moriya interaction. The spin-flop field H{sub c} of 7.5T is slightly lower than that in La{sub 2}CuO{sub 4}(H{sub c}{approx}10T), reflecting the decrease of the tilting angle of the CuO{sub 6} octahedra by the substitution of Sr{sup 2+} ion for La-site.
