摘要: Abstract Structural, AC and DC magnetic properties of polycrystalline Zn 1− x Co Fe 2 O 4 ( x= 0.2, 0.4) samples sintered at various temperatures (1100–1300 °C), dwell times (0.2–15 h) have been investigated thoroughly. The bulk density the 0.60 0.40 increases as sintering temperature T s ) from 1100 to 1250 °C, above 1250 °C decreases slightly. 0.80 0.20 show similar behavior changes that except is found be highest 1200 °C. magnetization a function curves sample ferrimagnetic room while paramagnetic temperature. c 170 K measurement. Separate measurement (AC magnetization), initial permeability shows 353 K. Slight variation observed depending on condition. for composition maximum.
