Recebido em 6/6/06; aceito em 15/3/07; publicado na web em 30/7/07The crystallization process of co-precipitated Y 1.5 Gd 1. . Dry pressed rings were sintered at 1270 and 1320 o C, increasing the grain-size from 3.1 to 6.5 μm, the theoretical density by 87.6 to 95.3% and decreasing H c from 2.9725 to 1.4005 Oe. Additionally, H c increased when the frequency of the hysteresis graph varied from 60 Hz to 10 kHz, the curie temperature was 282.4 o C and M s equalled 9.25 emu g -1 (0.17 kG) agreeing well with the B s -value of the hysteresis graph and literature values.
