Co-occurrence of Superparamagnetism and Anomalous Hall Effect in Highly Reduced Cobalt Doped Rutile TiO2 Films
S. R. Shinde, S. B. Ogale, J. S. Higgins +6
We report a detailed magnetic and structural analysis of highly reduced Co doped rutile TiO2 films displaying an anomalous Hall effect (AHE). The temperature and field dependence o…
Superconducting MgB2 thin films by pulsed laser deposition
S. R. Shinde, S. B. Ogale, R. L. Greene +5
Growth of MgB2 thin films by pulsed laser deposition is examined under ex situ and in situ processing conditions. For the ex situ process, Boron films grown by PLD were annealed at…
Optical Cooper Pair Breaking Spectroscopy of Cuprate Superconductors
Y. G. Zhao, Eric Li, Tom Wu +8
The photon energy dependence of optical Cooper pair breaking rate (CPBR) is studied for compressibly strained La1.85Sr0.15CuO4 (LSCO) films and YBa2Cu2.92Zn0.08O7-delta (YBCZO) thi…
Strain driven charge-ordered state in LaCaMnO
Amlan Biswas, M. Rajeswari, R. C. Srivastava +5
We present evidence for the coexistence of ferromagnetic metallic and charge ordered insulating phases in strained thin films of LaCaMnO at low temperatures.…
Is there a vortex-glass transition in high-temperature superconductors?
D. R. Strachan, M. C. Sullivan, P. Fournier +3
We show that DC voltage versus current measurements of a YBCO micro-bridge in a magnetic field can be collapsed onto scaling functions proposed by Fisher, Fisher, and Huse, as is w…
Evidence for the immobile bipolaron formation in the paramagnetic state of the magnetoresistive manganites
G. M. Zhao, Y. S. Wang, D. J. Kang +6
Recent research suggests that the charge carriers in the paramagnetic state of the magnetoresistive manganites are small polarons. Here we report studies of the oxygen-isotope effe…
Colossal electroresistance and electronic phase separation in mixed-valent manganites
T. Wu, S. B. Ogale, J. E. Garrison +6
The sensitivity of transport in CMR manganite to external fields is examined using a PZT-based field effect configuration with a La0.7Ca0.3MnO3 channel subjected to electric and ma…
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…
Low energy excitations in crystalline perovskite oxides: Evidence from noise experiments
Arindam Ghosh, A. K. Raychaudhuri, R. Sreekala +2
In this paper we report measurements of 1/f noise in a crystalline metallic oxide with perovskite structure down to 4.2K. The results show existence of localized excitations with a…
Optical Conductivity of Manganites: Crossover from Jahn-Teller Small Polaron to Coherent Transport in the Ferromagnetic State
M. Quijada, J. Cerne, J. R. Simpson +7
We report on the optical properties of the hole-doped manganites Nd_{0.7}Sr _{0.3}MnO_{3}, La_{0.7}Ca_{0.3}MnO_{3}, and La_{0.7}Sr_{0.3}MnO_{3}. The low-energy optical conductivity…
Standing Spin Wave Resonances in Manganite Films
S. E. Lofland, S. M. Bhagat, C. Kwon +3
We report the first observation of spin wave resonances in 110 nm thick films of LBMO. The spin wave stiffness follows = 47 (1 - 3 \times 10 ) meV.
