Description

The superconducting order parameter of Sr$_2$RuO$_4$ has again become a topic of great interest after recent NMR experiments have contradicted the once popular $p_x\pm i p_y$ spin-triplet superconducting state. We have previously explored a microscopic route to inter-orbital spin-triplet superconducting pairing with spin-orbit coupling to explain recent experimental data in Sr$_2$RuO$_4$ [1-3]. Here, we extend this microscopic theory to Sr$_3$Ru$_2$O$_7$, the bilayer version of Sr$_2$RuO$_4$ to explain why Sr$_3$Ru$_2$O$_7$ does not exhibit superconductivity, but spin-density wave order under a magnetic field.
