説明:

By means of x-ray absorption spectroscopic studies, both experimentally and theoretically, we investigated the magnetic properties of the transition-metal-only double perovskite oxide Mn2CoReO6, which experiences an antiferromagnetic transition at TN = 93 K whereas holds a considerable net moment at low temperature. Internal magnetic fields against the applied magnetic field for all the transition metal ions were identified, providing a microscopic insight of the intra-site antiferromagnetic couplings. Nevertheless, parallelly oriented canted spins of the Mn, Co and Re cations were observed. In particularly, the Mn and Co cations hold considerable canting moments, which can be ascribed to the competition between the ferromagnetic inter-site and antiferromagnetic intra-site magnetic interactions. Moreover, a linear magnetoresistance effect was observed below TN. The concurrence of the magnetoresistance effect and the antiferromagnetic nature make Mn2CoReO6 a promising candidate for high-speed and energy-saving spintronics applications.
