Electrical transport and magnetic properties of reactive sputtered polycrystalline Ti1−xCrxN films

The magnetoresistance (MR) and magnetic properties of (2 0 0) preferentially oriented Ti1-xCrxN films have been investigated systematically. All the films are ferromagnetic. The Curie temperature of the films is above 305 K, which is much higher than the previously reported value of 140 K in the Ti1...

Zusammenfassung:	The magnetoresistance (MR) and magnetic properties of (2 0 0) preferentially oriented Ti1-xCrxN films have been investigated systematically. All the films are ferromagnetic. The Curie temperature of the films is above 305 K, which is much higher than the previously reported value of 140 K in the Ti1-xCrxN systems. MR shows a weak saturation trend with the applied magnetic field, and increases significantly with a decrease in temperature below 50 K following the relation log
