| 摘 要： | 采用固相反应法制备了低温烧结NiCuZn铁氧体,研究了Co2+取代与Li+掺杂对NiCuZn铁氧体材料的饱和磁感应强度、剩磁、矫顽力、起始磁导率以及在直流偏置场下增量磁导率的影响.研究表明,适量的Co2+取代与Li1+掺杂会通过影响铁氧体材料的磁晶各向异性常数在一定程度上影响材料的磁导率.随着直流偏置场的增大,材料的磁...

| Abstract: | Low-temperature-fired NiCuZn ferrites were prepared by solid-state reaction method.The Effects of Co2+ substitution and Li+ doping on saturation magnetic flux density,remanence,coercivity,initial permeability and DC-bias-superposition characteristic were investigated.It was found that proper content of Co2+ substitution and Li+ doping can to some extent affect the permeability of the ferrite via magnetocrystalline anisotropy constant of the ferrite.Permeability of the ferrite continuously decreases with inc... |
