Spin gap and the nature of the 4d3 magnetic ground state in the frustrated fcc antiferromagnet Ba2YRuO6
Abstract
The geometrically frustrated double-perovskite Ba2YRuO6 has magnetic 4d3 Ru5+ ions decorating an undistorted face-centered-cubic lattice. This material has been previously reported to exhibit commensurate long-range antiferromagnetic order below TN∼ 36 K, a factor f∼15 times lower than its Curie-Weiss temperature ΘCW=−522 K, and purported short-range order to T*=47 K. We report new time-of-flight neutron spectroscopy of Ba2YRuO6 which shows the …
