Electrical Resistivity of SrRuO₃

Structural and transport properties of SrRuO3 thin films grown by MOCVD on (001) SrTiO3 substrates: The role of built-in strain and extra phases

“…The decrease of the resistivity with decreasing temperature (d (T)/dT > 0) indicates metallic behavior of the SrRuO 3 films. Our data concerning the shape of (T) and the break in slope at the phase transition temperature agrees well with the literature data for single crystals, polycrystalline (bulk) materials and thin films of SrRuO 3 [19][20][21][22][23]. A pronounced kink around 142 K is observed for the pure SrRuO 3 film (sample 1) which is interpreted as Curie point, below this point SrRuO 3 becomes ferromagnetic [24].…”

Thermoelectric Properties of Sr-Ru-O Compounds Prepared by Spark Plasma Sintering

“…The of the single-crystalline SrRuO 3 21) was higher than that of poly-crystalline in the present study by a factor of 2. The poly-crystalline SrRuO 3 prepared by SPS in this study and that reported by Maekawa et al 17) had higher by factor of 3 than that prepared by pressureless sintering, 22,23) probably due to the high density. Figure 5 shows the temperature dependence of the electrical conductivity of single-and poly-crystalline Sr 2 RuO 4 in literatures.…”

Structural and electrical properties of room temperature pulsed laser deposited and post-annealed thin SrRuO3 films

“…The resistivity is high for films post-annealed at 500°C (> 20 mΩ·cm), reaches minimum values for films post-annealed between 600°C and 700°C (∼ 2 mΩ·cm), and increases again for films post-deposited at temperature > 750°C. The minimum value of the resistivity measured has the same order of magnitude as reported for polycrystalline SRO films [23], i.e. 1130 μΩ·cm.…”
