Magnetic and transport properties of Pr0.8Ca0.2MnO3 crystal
Description
Magnetic and transport properties of Pr0.8Ca0.2MnO3 crystal have been studied. It was found that the magnetic anisotropy in (1 0 0) plane increases with decreasing temperature and increasing pressure. The resistivity for T>140 K obeys Arrhenius law with an activation energy Ea=130 meV, while at T<130 K, Ea=62 meV. The magnetoresistance maximizes near the Curie temperature of Mn moments TC1=130 K. The dynamic resistivity shows a marked dependence on a bias current I at T<TC1. The results are discussed in the frame of magnetic phase separation and spin-density wave scenario
