Williams α -CaCr 2 O 4 is a distorted triangular antiferromagnet. The magnetic Cr 3+ ions, which have spin-3 / 2 and interact with their nearest neighbors via Heisenberg direct exchange interactions, develop long-range magnetic order below T N =42.6 K. Powder and single-crystal neutron diffraction reveal a helical ma... [Phys. Rev. B 84, 054452] Published Mon Aug 15, 2011
