|Abstract:||We show that ac magnetoresistance at room temperature in La0.7 Sr0.3 MnO3 is extremely high (≈-47% in μ0 H=100 mT, f=3-5 MHz), and magnetic field dependence of reactance exhibits a double peak behavior. However, magnitudes of the ac magnetoresistance and magnetoreactance for a fixed length of the sample (li) decrease with decreasing separation (l v) between voltage probes unlike the dc magnetoresistance. On the contrary, change in li has a negligible influence on magnetoimpedance when lv is fixed. Our results indicate that high frequency electrical transport is sensitive to local variations in the magnetic permeability. © 2010 American Institute of Physics.|
