de Haas-van Alphen Effect in the Antiferromagnetic Compound GdIn_<b>3</b>

Abstract

We have measured the de Haas-van Alphen effect in the antiferromagnetic compound GdIn 3 . The Fermi surface of GdIn 3 is almost the same as that of the non- f reference compound LaIn 3 . The cyclotron masses of GdIn 3 are also close to those of LaIn 3 . These results indicate that the 4 f electrons in GdIn 3 are well localized and that mass enhancement due to the electron-magnon interaction is extremely small.
