## Detection of Striped Superconductors Using Magnetic Field Modulated Josephson Effect    [PDF]

Kun Yang
In a very interesting recent Letter\cite{berg}, the authors suggested that a novel form of superconducting state is realized in La\$_{2-x}\$Ba\$_x\$CuO\$_4\$ with \$x\$ close to 1/8. This suggestion was based on experiments\cite{li} on this compound which found predominantly two-dimensional (2D) characters of the superconducting state, with extremely weak interplane coupling. Later this specific form of superconducting state was termed striped superconductors\cite{berg08}. The purpose of this note is to point out that the suggested form\cite{berg} of the superconducting order parameter can be detected directly using magnetic field modulated Josephson effect.
