ABSTRACT
The ac electrical impedance of a 400-nm-thick La[sub 0.67]Sr[sub 0.33]MnO[sub 3] thin film (on MgO) has been measured in the frequency range from 30 MHz up to 6 GHz using etched strips. The impedance is found to be nearly a constant resistance that is equal to the dc resistance. The only deviations, in the order of their magnitude, are: (i) the contact pad impedance at low frequency, (ii) a small inductive part in the impedance of the material, and (iii) a low decrease of the resistance above 3 GHz. © 2003 American Institute of Physics.
