Galvanomagnetic properties of transition metal-boron films
Abstract
The Hall effect and the anisotropic magnetoresistance have been studied in Fe-B, Co-B and Co-Ni-B films. These are sputtered films with boron content from 5 to 37% and are only amorphous when B is above 15%. In all cases the alloys are ferromagnetic at room temperature. Amorphous FeB has both the largest Hall angle and magnetoresistance. Co-B and Co-Ni-B have only one third the values found for Fe-B. The Co-Ni-B system is mostly crystalline but the resistivity is nearly as large as the amorphous binary alloys. © 1980 IEEE
