Abstract
We have observed the double-spin-flip mode, corresponding to one photon fli pping two nuclear spins, in rhodium with low-frequency SQUID NMR at ultralo w temperatures. The shift and magnitude of the absorption line at around tw ice the Larmor frequency has been studied. The shift of the double-spin-fli p mode can be used to calculate the relative strength of the Ruderman-Kitte l exchange interaction, for which we obtain R = - 0.9 +/- 0.1.
