Elastic behaviour of BiPbAgCa2CuO3 superconducting composite materials

Distinct effects of Al3+ substitution at Cu-site and Al2O3 addition on step-like elastic anomalies and electron–phonon coupling constant in EuBa2Cu3O7−δ superconductors

“…In the composite, Al 2 O 3 exists as a separate phase and is not expected to enter the Eu123 lattice structure. This is in agreement with previous report on elastic behavior of (BiPb) 2 Sr 2 Ca 2 Cu 3 O 10 /AgCa 2 CuO 3 composite [42]. In the present work, it is suggested that Al 2 O 3 resides along Eu123 grain boundaries and alters bonding strength between grains which in turn affects elasticity of the composite material.…”

Elastic behavior of some manganite-based orthorhombic RMnO3 (R=Sm, Eu, Gd, Dy) multiferroics

“…It can be seen from the table that y D values are found to increase with V m . A similar behavior between Debye temperature and average velocity has been observed in the case of some ferrites [19] and high T c superconductors [20,21].…”

Elastic behavior of La0.67Ca0.33MnO3:ZrO2 composites

“…1. It is interesting to note that there is a linear relationship and the behavior is found to be similar to that of several other ceramic oxides such as TiO 2 , Fe 2 O 3 , zirconia, garnets, ferrites [13], HTSC materials [14,15], etc.…”
