The effect of Al substitution for Fe on the spin reorientation and Mssbauer spectra of a series of Tb03Dy07(Fe1-xAlx)195 alloys (x=005,01,015,020,025,030,035) at room temperature and 77K has been investigated systematically. The results indicate that the easy magnetization direction in the 100 plane deviates slightly from the main axis of symmetry, namely spin rerioentation. A small amount of non_magnetic phase exists for x=015, and the alloys become paramagnetism when x>015 at room temperture, but at 77K the alloys still remain to be magnetic phase even at x=02. At room temperature and 77K, the hyperfine field decreases and the isomer shift increases with increasing concentration of Al, and the quaduple splitting QS shows weak concentration dependence.
