Study of the transport properties and magnetic anisotropy of Fe73 Cu1 Nb3.5 Si14 B8.5 metglass

Abstract

The transport properties of the metallic glass Fe73Cu ISiI4Nb3.5Bg,5 are investigated in different applied magnetic fields and temperatures, The Han resistivity and the magnetoresistanee coefficients have been evaluated for differelll applied magnetic fields and temperatures, The magnetic anisotropy of this 'system. which is induced in this system due to mechanical wess at the time of growth are also detenllined by measuring the magnetic torque on this sy~iem_ A torque magnetometer with an automatic electronic compensation sy&temand a high temperature Oven has been used for lhis measurements The temperature dependence of magnetic anisotropy has al,o been studied. The magnetoresistance coefficient and the Han re&istivity are observed to have anomalous behaviour, and the anomalies are expected to be caused by rapid spin fluctuations in this mctallic glass ,ystem. rhe magnetisation measurement of tbe metallic glass with different annealed temperatures is done by using the Vibrating Sample Maguetometer(VSM),
