초록

In this research, the structural, physical and electrical characteristics of Ni-Fe core chosen to minimize the errors of the Hall current sensors were investigated and Hall current sensor using Ni-Fe core was fabricated. In the result, the fabricated Ni-Fe sample exhibited the maximum hardness about 29.5 GPa and the low friction coefficient about 0.35, and electrical resistivity over $90mOhm{\cdot}cm$. And also Hall current sensor using the fabricated Ni-Fe core showed linear current-voltage properties for DC current at $25^{\circ}C$ temperature.
