โœฆ Synopsis

The electron paramagnetic resonance (EPR) spectra of Pr 4; diluted in Sr 2 CeO 4 were measured at 4.2 K. A very large hyperfine interaction with the 141 Pr nucleus was observed. The spectra were anisotropic, due to the distortion of the octahedral oxygen coordination symmetry around the Pr 4ุ‰ ion. The results were analyzed based on the weak field approximation, and the following g values and hyperfine coupling constants A were obtained: " "g # # " " โ€ซุโ€ฌ 1.169, " "g N N " " โ€ซุโ€ฌ 0.966, " " A # # " " โ€ซุโ€ฌ 0.0703 cm ุŠ1 , and "A N N " โ€ซุโ€ฌ 0.0669 cm ุŠ1 . The measured g values are smaller than " "ุŠ10/7" ", showing that the crystal field is effective to some extent on the behavior of a 4f electron in Sr 2 CeO 4 .
