Microwave absorption measurements in the complex perovskite Pb(Fe0.5Ta0.5)O3: Detection of short-range orderly regions

An electron paramagnetic resonance (EPR) study of the complex perovskite Pb(Fe0.5Ta0.5)O3 (PFT) at X-band (8.8-9.8GHz) is presented. The EPR spectra show a single broad line in the 300-480K temperature range, attributable to Fe3+ (S=5/2) ions. The temperature dependence of the EPR parameters: the pe...
