Magnetic and Structural Properties of GdFe1–xTixSi

Si, x = 0-0.2, intermetallic compounds with a tetragonal crystal structure of the CeFeSi (P4/nmm)type were studied. With increasing Ti content, the lattice parameter c and the Curie temperature both increase quickly for 0 <; x <; 0.1 and then more moderately for 0.1 <; x <; 0.2 whereas, the lattice parameter a is almost unchanged. The GdFeSi is compound easily magnetized along the [001] axis. The magnetic anisotropy field is about 3.8 kOe at T = 90 K for GdFeSi and vanishes in GdFe

Si. The saturation magnetization does not change over the range 0 <; x <; 0.2.
