Hyperfine magnetic field measurements in ErRh/sub 4/B/sub 4/

Conference ·
OSTI ID:6379020
Measurements of the hyperfine magnetic field in ErRh/sub 4/B/sub 4/ in zero applied field are reported in a range of temperatures around the reentrant temperature T/sub c2/. Using the Moessbauer effect of /sup 57/Fe impurities as a hyperfine field microprobe, the low temperature ferromagnetic order is found to persist well above T/sub c2/ into the superconducting state in this compound, thereby providing direct evidence of coexistence between superconductivity and magnetic order.
