Magnetic properties lithium-doped manganite single crystals
Magnetic and resistivity properties of La₁₋xLixMnO₃ single crystals with the perovskite structure at lithium concentrations x=0.06 and 0.2 are investigated over a broad temperature range at fields of up to 50 kOe. The Curie temperature is TC=90 K (x=0.06) and 300 K (x=0.2), respectively. The electri...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Magnetic and resistivity properties of La₁₋xLixMnO₃ single crystals with the perovskite structure at lithium concentrations x=0.06 and 0.2 are investigated over a broad temperature range at fields of up to 50 kOe. The Curie temperature is TC=90 K (x=0.06) and 300 K (x=0.2), respectively. The electrical resistance of the single crystal with x=0.06 increases steadily with temperature decrease, while the crystal with x=0.2 exhibits a magnetoresistance effect of ~ 8% at an external field of 9 kOe. The different dependence of the magnetizations MFC and MZFC of the sample with lower lithium content in the temperature range below TC is associated with the formation of a cluster glass and is caused by high coercivity and magnetic anisotropy of the crystal. |
