Investigation of the influence of field-induced phase-separation in LSCO+O on...

The mechanism behind superconductivity in La(2-x)Sr(x)CuO4 (LSCO) and La(2-x)Sr(x)CuO(4+y) LSCO+O is still unknown. Recently a phonon-anomaly in the Cu-O bond-stretching mode...La₂₋ₓSrₓCuO₄（LSCO）与La₂₋ₓSrₓCuO₄₊ᵧ（LSCO+O）的超导微观机制至今仍未阐明。近期，Cu-O键拉伸模式中存在的声子反常现象……
