Determination of magnetoimpedance characteristics of the materials produced by sol-gel method

In this study generally LaSrMnO3, LaBaMnO3 similar samples were prepared by sol-gel method. Manganite samples prepared by dip-coating on platinum wire in different diameters and lengths are coated using the method. To determine the structural properties of the prepared samples were measured by means of X-rays. Magneto Impedance characteristics of the impedance characteristics depending on magnetic field and frequency is set. Percent change in magnetic impedance frequencies up to 5 MHz operation was observed. Percent in value over and above that frequency has changed depending on the thickness of the magnetic impedance changes. The biggest percentage change of magneto-impedance 0.3 mm thick coated with a platinum wire was observed in samples La0.67Sr0.33MnO3 worth 80 MHz frequency. La0.67Sr0.33MnO3 samples La0.67Ba0.33MnO3 sample showed a higher percent change compared to manyetoempedans.
