Magnetic Resonance of a Localized Magnetic Moment in the Superconducting State: La Ru2 :Gd

Open publisher page 43 citations

Abstract

The magnetic resonance of dilute La${\mathrm{Ru}}_{2}$:Gd has been observed in both the superconducting and normal states. A reduction in the $g$ shift and an increase in the thermal broadening were observed, upon going from the normal to the superconducting regime. The spin-orbit scattering rate, $\frac{1}{{\ensuremath{\tau}}_{\mathrm{s}.\mathrm{o}.}}$, is estimated from both EPR and the re-entrant behavior of the upper critical field in La${\mathrm{Ru}}_{2}$:Gd.
