The hydrothermal synthesis of lanthanum manganites, La1-xSrxMnO3+delta, was investigated for x = 0 and x = 0.2, under autogenous pressure in the temperature range 140-240degreesC, varying the time (2 - 410 hours) and the nature of the metal precursors and of the base. Several pathways...
Insulator-metal transition and giant magnetoresistance in La1-xSrxMnO3. Insulator-metal phenomena depending on band filling (doping degree), temperature, and external magnetic field have been investigated for prototypical doubl... A Urushibara,Y Moritomo,T Arima,... - 《Physical Review B Condense...
X Guo,Z Chen,S Dai,Y Zhou,H Cheng 摘要: The transport and magnetic properties of perovskite-type epitaxial films of (La1-xSnx)yMnO3-delta have been studied. The results of the resistivity, magnetization, and Curie temperature as a function of the tin concentration show that the tin in ...
