However, the twin structure existing in the ab plane of RE BCO complicates the dependence of critical current density on temperature, magnetic field, and uniaxial strain: ##IMG## [http://ej.iop.org/images/0953-2048/33/9/094014/sustaba352ieqn3.gif] {$J_{\rm c}(T,B,\varepsilon)$} . In particular, the mechanism for the appearance of anomalous double-peak structure in ##IMG## [http://ej.iop.org/images/0953-2048/33/9/094014/sustaba352ieqn4.gif] {$J_{\rm c}(T,B,\varepsilon)$} is unclear.
