Room-temperature magnetic Heusler compound Fe2Ti0.5Co0.5Si with semiconducting behavior
Source abstract
Abstract
Abstract The structural, magnetic and electron-transport properties of Fe2Ti0.5Co0.5Si are investigated. It is demonstrated that rapidly quenched Fe2Ti0.5Co0.5Si ribbons crystallize in the L21 structure, indicating a full Heusler compound, and exhibit ferromagnetism with a high Curie temperature of about 790 K. Moreover, Fe2Ti0.5Co0.5Si exhibits semiconducting behavior with a negative temperature coefficient of resistivity, a room-temperature resistivity of about 6.5 mΩ cm and a residual resistivity ρ0 of about 6.75 mΩ cm. The carrier concentration n is 1.15 × 1020 cm−3 at 5 K. The magnetic semiconducting behavior with a high Curie temperature makes this material promising for room-temperature spintronic and magnetic applications.
