Abstract

The external field dependence of the hyperfine field at La-site has been studied on La2-xSrxCuO4(x=0.115) and La2-xBaxCuO4(x=0.125), where the magnetic ordering in Cu-3d spins exists at low temperature. In La1.885Sr0.115CuO4, a significant decrease in the resonance line width was observed above a field of Hc ≈ 7.5T, which is the direct evidence of the spin-flop in the canted-spin system with Dzyaloshinski-Moriya interaction. The spin-flop field Hc of 7.5T is slightly lower than that in La2CuO4(Hc ≈ 10T), reflecting the decrease of the tilting angle of the CuO6 octahedra by the substitution of Sr2+ ion for La-site.
