Magnetic fields and the spin fluctuations in CeRhSi3 – Field induced spin resonance and possible analogy to YbRh2Si2
The proposal requests 7 days to study the magnetic field dependence of the spin fluctuations in CeRhSi3 on IN12. Recent momentum surveys have found that the fluctuations are located near ferromagnetic positions and cross over to incommensurate momentum positions with decreasing temperature. The situation is analogous to YbRh2Si2 where a field induced resonance has been observed. Motivated by this unusual discovery in YbRh2Si2, we propose to investigate the field dependence of the spin fluctuations in CeRhSi3 to search for similar responses. IN12 is required for this experiment as we need long wavelengths (and good energy resoluation) and in particular to be below the Bragg cutoff for Al to avoid background from the sample mount.
