Abstract

Using the phenomenon of ferromagnetic antiresonance (FMAR) in ceramic samples of La_0.67Ba_0.33MnO₃ at 10 GHz, we report a large magneto-impedance MI=R_s(H_l) -R_s(H_⊥)/R_s(H_l), where R_s is the microwave surface resistance and H the applied field. The MI reaches 30% at a field of 30 mT near room temperature. The FMAR also lets us measure M(T) by following R_s as a function of T and H.
