Unlocking the Mystery of Spontaneous Magnetism in a Superconductor
![The study demonstrates a correlation between the enhanced muon spin depolarization rate [latex]\Delta\lambda(T=0)[/latex] in strontium ruthenate and its derivatives, and the density of inhomogeneities or defects, suggesting [latex]\Delta\lambda(T=0)\propto nJ_{s}[/latex], where [latex]n[/latex] represents this density and [latex]J_{s}[/latex] the strength of spontaneous currents; specifically, La-doped samples and those under hydrostatic pressure maintain a relatively constant defect density, resulting in a depolarization rate proportional to the square of the critical temperature [latex]\Delta\lambda\propto T_{c}^{2}[/latex], while samples containing ruthenium inclusions or exhibiting random disorder demonstrate significantly enhanced depolarization rates driven by increased defect density.](https://arxiv.org/html/2512.24585v1/x3.png)
