Transport properties of beta-Fe1-xMnxSi2 alloys
16 September 2000
The results of transport measurements on beta-Fe1-xMnxSi2 alloys in the temperature range of 80 to 300 It are presented and explained assuming the existence of an impurity band. The values of the activation energies of the shallow and deep accepters, their concentrations, the concentration of the compensating donors as well as the impurity band width were calculated.
