The electron paramagnetic resonance spectra of powders with the Pr 4؉ ions doped in the B sites of the pyrochlore-type compounds A 2 B 2 O 7 (A ‫؍‬ La; B ‫؍‬ Sn or Zr) were successfully measured at 4.2 K. A very large hyperfine interaction with the 141 Pr nucleus was observed. The spectra were isotr
