Li-Zn-Cu和Li-Zn-Co系铁氧体Mossbauer效应研究

Study on Li-Zn-Cu and Li-Zn-Co ferrites mossbauer effect

在室温条件下 ,测量了多晶铁氧体 (Li0 .5Fe0 .5) 0 .7 xZn0 .3CuxFe2 O4(x =0 .0 ;0 .0 3 ;0 .0 5 ;0 .0 7)和 (Li0 .5Fe0 .5) 0 .7 yZn0 .3CoyFe2 O4(y =0 .0 ;0 .0 1 ;0 .0 2 ;0 .0 3 )的Mossbauer谱 ,结果表明 ,离子代换使样品的Mossbauer谱变得复杂。

Mossbauer\|spectra of the polycrystalline ferrites (Li\-\{0.5\}Fe\-\{0.5\})\-\{0.7\|x\}Zn\-\{0.3\}Cu\-xFe\-2O\-4(x=0.0;\{0.03;\}0.05;0.07) and (Li\-\{0.5\}Fe\-\{0.5\})\-\{0.7\|y\}Zn\-\{0.3\}Co\-yFe\-2O\-4(y=0.0;0.01;0.02;0.03) under room\|temperature are measured. The results show that the Mossbauer\|spectra of the samples get more complicated with ion\|substitution. Each line of the spectra contains 1 set of paramagnetic doublet subspectra with weak intensity.
