μ+SR studies on thermoelectric oxides

Description

To investigate the role of magnetism on transport properties of thermoelectric oxides, μ+SR spectroscopy has been used for polycrystalline Ca3Co4O9, Na0.7CoO2 and Sr0.92-yCayGd0.08MnO3 samples in the temperature range between 300 and 2.5 K. It was found that Ca3Co4O9 exhibits an incommensurate spin density wave transition around 100 K, though similar measurements on Na0.7CoO2 indicated no magnetic transitions below 250 K. The Sr0.92-yCayGd0.08MnO3 samples showed a ferro- or an antiferromagnetic transition below 250 K, while a muon precession was not observed even at 2.5 K probably due to an inhomogeneity of an internal magnetic field
