Enhanced Ferromagnetic Ordering in GdBaCoO Films on SrTiO3 (001) Substrate
G. Y. Wang, X. Y. Zhou, R. K. Zheng +3
The authors investigated the structure and properties of GdBaCoO thin films epitaxially grown on SrTiO (001) single crystal substrates. The thin films were fo…
The transport, ultrasound, and structural properties for the charge ordered Pr1-xCaxMnO3 (0.5<=x<=0.875) manganites
R. K. Zheng, G. Li, Y. Yang +4
The effects of the cooperative Jahn-Teller effect on the crystal structure and the stability of the charge ordered (CO) state were studied by measurements of powder X-ray diffracti…
The role of the cooperative Jahn-Teller effect in the charge ordered La1-xCaxMnO3 (0.5<=x<=0.87) manganites
R. K. Zheng, G. Li, A. N. Tang +5
Based on the magnetoresistance, magnetization, ultrasound, and crystallographic data, we studied the role of the cooperative Jahn-Teller effect in the charge ordered (CO) state for…
Insulator-metal transition shift related to magnetic polarons in La0.67-xYxCa0.33MnO3
G. Li, S. -J. Feng, F. Liu +5
The magnetic transport properties have been measured for La0.67-xYxCa0.33MnO3 (0 <= x <= 0.14) system. It was found that the transition temperature Tp almost linearly moves to high…
Internal friction and Jahn-Teller effect in the charge-ordered La1-xCaxMnO3 (0.5<x<0.87)
R. K. Zheng, R. X. Huang, A. N. Tang +5
The Jahn-Teller effect in the charge-ordered (CO) state for La1-xCaxMnO3 (0.5<x<0.87) was studied by measuring the low-temperature powder x-ray diffraction, internal friction, and…
Jahn-Teller effect and stability of the charge-ordered state in La1-xCaxMnO3 (0.5<x<0.9) manganites
X. G. Li, R. K. Zheng, G. Li +4
The longitudinal ultrasonic sound velocity and attenuation, the resistivity, and lattice parameters were studied as a function of temperature from 30 K to 300 K in La1-xCaxMnO3 (0.…
