Magnetic properties of liquid Ti-Si, V-Si and Cr-Si alloys

The magnetic susceptibilities of liquid Ti-Si, V-Si and Cr-Si alloys have been measured as a function of composition and temperature. The magnetic susceptibilities were found to be almost independent of temperature, which suggests that transition metal solutes in liquid Si are in the non-magnetic state. The impurity susceptibilities were estimated under the assumption that the solute atoms are monovalent in liquid Si. The general trend obtained for the whole series of 3d solutes in liquid Si shows a sharp peak around Mn solute which is considerably less pronounced than that reported in liquid In or Sn. The results are discussed in terms of Anderson's model of localized impurity states.
