Decoupling lattice and magnetic instabilities in frustrated CuMnO
Keith V. Lawler, Dean Smith, Shaun R. Evans +8
The MnO delafossites (=Na, Cu), are model frustrated antiferromagnets, with triangular layers of Mn~spins. At low temperatures (=65 K), a $C2/m \rightarro…
Origin of anomalous breakdown of Bloch's rule in the Mott-Hubbard insulator MnTe
Tapan Chatterji, Antonio M. dos Santos, Jamie J. Molaison +5
We reinvestigate the pressure dependence of the crystal structure and antiferromagnetic phase transition in MnTe by the rigorous and reliable tool of high pressure neutron powd…
Giant atomic displacement induced by built-in strain in metastable MnO
Shigeto Hirai, Antonio M. dos Santos, Maxwell C. Shapiro +6
We present x-ray, neutron scattering and heat capacity data that reveal a coupled first-order magnetic and structural phase transition of the metastable mixed-valence post-spinel c…
