Effects of Co2O3 concentration on high Q-factor NiCuZn ferrites for 13.56 MHz radio identification communication
Source abstract
Abstract
Abstract Co 2 O 3 -doped NiCuZn ferrites with a high (group A) or low (group B) permeability were prepared using the conventional ceramic method to obtain high Q -factor NiCuZn ferrites for a 13.56 MHz near-field-communication (NFC) system. The XRD patterns of samples from both groups exhibited single spinel phase. Permeability monotonously decreased with increasing Co 2 O 3 content, whereas sintering density and saturation magnetic flux density (Bs) slightly changed with Co 2 O 3 content. The permeability of 0.45 wt% Co 2 O 3 -doped ferrite (A 0.45 ) was similar to that of 0.10 wt% Co 2 O 3 -doped ferrite (B 0.10 ). However, the former sample presented a considerably higher Q- factor than the latter sample. The former sample also presented enhanced stability variation of Q -factor with frequency, which indicated an improved electromagnetic shielding function for the NFC system. The mechanisms involved were also elucidated.
