Abstract

The quantum magnet KOsO₄ has been characterized by a combination of X-ray and neutron diffraction techniques. The tetrahedrally coordinated Os⁷⁺ 5d¹S = 1/2 cations were determined to order antiferromagnetically along the c axis below 35 K. A miniscule ordered magnetic moment of 0.46(18) μ_B was determined per Os⁷⁺ cation.
