Room temperature giant magnetoimpedance in polycrystalline La0.75Ba0.25MnO3
We report the magnetic field dependence of electrical impedance Z in polycrystalline La0.75Ba0.25MnO3 a function of frequency from f = 1 MHz to 1 GHz at room temperature. The magnetoimpedance [MI = ΔZ/Z(0) where ΔZ = Z(H)-Z(0)] is −37.5 % (-58.5%) at 1(10) MHz for H = 1.2 kOe, which far exceeds mere...
