Role of Sm3+ Addition on Humidity Sensing of Nanocrtsyallite Mg-Cd Ferrites

摘要：

　　Nanocrystallite powders of 5 wt% Sm3+ added Mg-Cd ferrite samples were prepared by oxalate co-precipitation method.XRD,SEM and FT-IR techniques were used for characterization of the samples.The XRD reveals cubic spinel nature with secondary phase (SmFeO3).The crystailite size lies in the range of 28.69 to 32.66 nm.All the Sm3+ ions added samples are humidity sensitive at low humidity range 40 to70 %RH.The electrical resistivity of Sm3+ ions added samples decreased by four orders of magnitude,when %RH increased from 40%RH to 90 %RH.The response and recovery time of all the samples are 160-290 sec.The shorter response time was observed for Sm3+ added Cd ferrite sensor.
