Magnetic penetration depth in electron-doped cuprates - evidence for gap nodes
R. Prozorov, R. W. Giannetta, P. Fournier +1
The in-plane penetration depth λ(T) is measured in electron-doped single crystals Nd1.85Ce0.15CuO4-x (NCCO) and Pr1.85Ce0.15CuO4-x (PCCO) using a 11 MHz LC resonator. In NCCO, λ(T)…
Two-phase behavior in strained thin films of hole-doped manganites
Amlan Biswas, M. Rajeswari, R. C. Srivastava +4
We present a study of the effect of biaxial strain on the electrical and magnetic properties of thin films of manganites. We observe that manganite films grown under biaxial compre…
Temperature dependent scattering rate and optical mass of ferromagnetic metallic manganites
J. R. Simpson, H. D. Drew, V. N. Smolyaninova +4
We report on the optical properties of the hole-doped manganites La_0.7Ca_0.3MnO_3 and La_0.7Ca_0.3MnO_3. Transmission and reflection of thin films are measured in the infrared at…
Effects of annealing and strain on La_{1-x}Ca_{x}MnO_{3} thin films: a new phase diagram in the ferromagnetic region
W. Prellier, M. Rajeswari, T. Venkatesan +1
Oriented, single phase thin films of La_{1-x}Ca_{x}MnO_{3} have been deposited onto (100)-oriented LaAlO_{3} (0.1<x<0.5) substrates using the Pulsed Laser Deposition technique. Whi…
Properties of the ferrimagnetic double-perovskite A_{2}FeReO_{6} (A=Ba and Ca)
W. Prellier, V. Smolyaninova, Amlan Biswas +4
Ceramics of A_{2}FeReO_{6} double-perovskite have been prepared and studied for A=Ba and Ca. Ba_{2}FeReO_{6} has a cubic structure (Fm3m) with 8.0854(1) Åwhereas Ca_{2}F…
The effect of substrate induced strain on the charge-ordering transition in Nd_{0.5}Sr_{0.5}MnO_{3} thin films
W. Prellier, Amlan Biswas, M. Rajeswari +2
We report the synthesis and characterization of Nd_{0.5}Sr_{0.5}MnO_{3} thin films grown by the Pulsed Laser Deposition technique on 100 -oriented LaAlO_{3} substrates. X-ray diffr…
