Sažetak
We have measured the magnetic susceptibility, resistivity, magnetoresistivity and Hall effect of nonstoichiometric cuprous selenide between 5 K and 350 K. Our results show that below 170 K Cu_(2-x)Se is a mixture of diamagnetic Cu_1.995Se and paramagnetic Cu_3Se_2. The phase diagram of the Cu-Se system, in which 170 K represents the eutectic isotherm, governs the relative content of the two phases. For the Cu_3Se_2 phase a transition to an antiferromagnetic state is observed at about 50 K, with the corresponding Weiss temperature 120 K. On heating above 170 K Cu_(2-x)Se becomes completely diamagnetic, but the transformation is slow and strongly time dependent. The complicated magnetic behaviour is ascribed to a broad temperature hysteresis of the process.
