Physical properties of single-crystalline fibers of the colossal-magnetoresistance manganite La0.7Ca0.3MnO3
C. A. Cardoso, F. M. Araujo-Moreira, M. R. B. Andreeta +5
We have grown high-quality single crystals of the colossal-magnetoresistance (CMR) material La0.7Ca0.3MnO3 by using the laser heated pedestal growth (LHPG) method. Samples were gro…
Disorder effects at low temperatures in La_{0.7-x}Y_{x}Ca_{0.3}MnO_{3} manganites
M. A. Gusmao, L. Ghivelder, R. S. Freitas +4
With the aim of probing the effect of magnetic disorder in the low-temperature excitations of manganites, specific-heat measurements were performed in zero field, and in magnetic f…
Spin Glass Behavior in the Ru-1222 and Ru-1212 rutheno-cuprate families: a comparative study
C. A. Cardoso, F. M. Araujo-Moreira, V. P. S. Awana +3
Strong evidences of a spin glass phase on polycrystalline RuSr2Ln1.5Ce0.5Cu2O10-x (LnRu-1222, Ln = Y, Ho and Dy) is provided by ac susceptibility and dc magnetization measurements.…
