Magnetic and Transport Properties of La$_{0.7}$Ca$_{0.3}$MnO$_{3}$ Films Controlled by Structural Disorder

V. G. Prokhorov; YoungPak Lee; 조광환; S. Y. Park; V. A. Komashko; V. L. Svetchnikov (The Korean Physical Society, 2004-07)

The magnetic and the transport properties of an amorphous, a partially amorphous and a latticestrained crystalline La0:7Ca0:3MnO3 lm have been investigated. It was shown that the amorphous lm exhibited Pauli paramagnetism ...
Observations of Reduced Microwave Surface Resistance for YBa2Cu3O7？\delta Films Grown on CeO2-Buffered R-Cut Sapphire

J. H. Lee; Sang Young Lee; V. A. Komashko (The Korean Physical Society, 2006-05)

Availability of high-temperature superconductor (HTS) films with a critical temperature of 90 K and a surface resistance of 300 μ at 10 GHz and 77 K has enabled the use of superconducting microwave devices for mobile ...
Spin and Charge Ordering in La1-xCaxMnO3 (x = 0.5 and 0.6) Thin Films

V. G. Prokhorov; Jeong Soo Park; K. K. Yu; S. Y. Park; V. A. Komashko; V. L. Svetchnikov; YoungPak Lee (The Korean Physical Society, 2006-06)

The magnetic and the transport properties of La0.5Ca0.5MnO3 and La0.4Ca0.6MnO3 films with different thickness were investigated. The electron-diffraction study showed that the charge-ordered phase was observed at room ...
Structural Clustering and Magnetic Phase Separation in La0.7(Ca1-ySry)0.3MnO3 Thin Films

V. G. Prokhorov; Jeong Soo Park; J.-H. Kang; K. K. Yu; S. Y. Park; V. A. Komashko; V. L. Svetchnikov; YoungPak Lee (The Korean Physical Society, 2006-06)

The structural, magnetic, and transport properties of the La0.7(Ca1.ySry)0.3MnO3 films prepared by rf-magnetron sputtering have been investigated. At 0.3 y 0.5, both the rhombohedral (R3c) and orthorhombic (Pnma) ...
