Uniaxial Stress Effect on the Superconductivity of Grain-Aligned Composites of La_2−xSr_xCuO₄

抄録

The uniaxial stress effect on the superconductivity of grain-aligned samples of La_2−xSr_xCuO₄ prepared by a “magnetic-field-induced alignment” method has been investigated. The T_c decreases with increasing uniaxial stress along the “c-axis”. The result indicates that the in-plane O–O or Cu–O bond length should significantly affect its superconductivity.
