Abstract The ferromagnetic antiresonance (FMAR) phenomenon, i.e., the minimum of the microwave absorption, in polycrystalline La0.49Sr0.51MnO3 is observed near Curie temperature TC = 282K. Temperature-dependences of magnetization μ0M are obtained from the FMAR. The results show that as
μ0H =0, by fitting the scaling law M∝(TC-T)β to temperature-dependences of μ0M at the different microwave frequencies, it yields TC = 281.2K and β= 0.47. However, temperature-dependences of β0M under different β0H are not
in agreement with the scaling law. Due to FMAR, about 40% giant microwave magneto-impedance at 11.9GHz can occur under a low field μ0H=0.03T.
