It is found that interaction between different components of the microwave fields and the manganite distorts the shape of resonance lines and changes the resonance-to-antiresonance amplitude ratio. In the range of ferromagnetic resonance fields, great (up to 25 times) changes in the transmitted microwave power are observed Полный текст |
