Anomalous Nernst effect in the ceramic and thin film samples of La0.7Sr0.3CoO3 perovskite
Original language description
We report the anomalous Nernst effect (ANE) in large-grain ceramics, nanogranular ceramics, and nanogranular thin films of La0.7Sr0.3CoO3, measured over the temperature range 5–300 K. The study is complemented with thermopower, resistivity, and magnetic measurements. The temperature-dependent ANE below the Curie temperature TC (240–250 K) is analyzed with the help of longitudinal resistivity and Seebeck using a previously proposed formula derived by a combination of Onsager reciprocity, the Mott formula, and the relation between transverse and longitudinal resistivity, ρxy∝ρnxx. We observe a characteristic exponent n ∼ 0.4 in agreement with the universal scaling for the bad-metal-type conduction regime. The nanogranular samples are characterized by higher resistivity, lower saturated magnetization, and a higher coercive field compared to large-grain ceramics.n
