Magnetic Properties of lT-TaS₂

The magnetic properties of 1T-TaS₂ and 1T-Fe_0.07Ta_0.93S₂ have been studied. Experimental results show that the phase transition temperature of IT-TaS₂ is a function of the magnetic field. At low temperatures, both compounds are in a mixed state of charge density wave -spin density wave due to the coherent superposition of antifer-romagnetic coupling.
