The electrical conductivity of pristine, La-, and Nb-doped SFM measured in air and hydrogen atmospheres

This dataset consists of an Excel sheet with the result of DC4W method of electrical measurements. The measurements were conducted on pristine strontium ferrite molubdate as well as ones doped with La and Nb. Additionally two samples co-doped with La and Ni/Co were analyzed. Pellets were prepared by high temperature sintering at 1400 deg. C, then cut into rectangles. Platinum electrodes were mounted and samples were put into the measurement cell. Firstly sample were heated up to 900 deg. C in air, then datapoints were collected during cooling. Each temperature was hold for several hours to allow relaxation. Then the gas was switched to inert gas, to rinse the cell before enabling the hydrogen flow. Same procedure was repeated for hydrogen atmosphere.
