The de Haas van Alphen effect was investigated in the antiferromagnatic com
pound GdIn3. A number of Fermi surface branches were observed. The list of
the all detected frequencies and related cyclotron masses is given. The ani
sotropy of the critical field connected with the observed metamagnetic tran
sition was measured. The angular dependence of this anisotropy shows that m
agnetic moment alignment in GdIn3 is probably tilted by 5 degree from the [
111] direction.
