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…

Specific heat and magnetic order in LaMnO_{3+δ}
L. Ghivelder, I. Abrego Castillo, M. A. Gusmao +2
Magnetic and specific-heat measurements are performed in three different samples of LaMnO_{3+δ}, with δ=0.11, 0.15 and 0.26, presenting important disorder effects, such as carrier…
