Magnetic properties of high-symmetry CuO

Magnetic properties of high-symmetry CuO

We investigated structural and magnetic properties of CuO-Cu2O heterostructures obtained by high-temperature annealing of copperplate. In samples synthesized at 900 °C, an antiferromagnetic alignment phase was found at the Neel temperature TN = 600 K in fields greater than 20 Oe. At lower fields, di...

Zusammenfassung:We investigated structural and magnetic properties of CuO-Cu2O heterostructures obtained by high-temperature annealing of copperplate. In samples synthesized at 900 °C, an antiferromagnetic alignment phase was found at the Neel temperature TN = 600 K in fields greater than 20 Oe. At lower fields, diamagnetic alignment was observed at 680 K. The cubic phase of CuO appears to be responsible for the diamagnetic transition and the high Neel temperature.
