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…
Pressure induced topological quantum phase transition in Weyl semimetal T_d-MoTe_2
Z. Guguchia, A. M. dos Santos, F. O. von Rohr +11
We report the pressure (p_max = 1.5 GPa) evolution of the crystal structure of the Weyl semimetal T_d-MoTe_2 by means of neutron diffraction experiments. We find that the fundament…
Exploiting symmetry-mismatch to control magnetism in a ferroelastic heterostructure
Er-Jia Guo, Ryan Desautels, Dongkyu Lee +11
In the bulk, LaCoO3 (LCO) is a paramagnet, yet in tensile strained thin films at low temperature ferromagnetism (FM) is observed, and its origin remains unresolved. Polarized neutr…
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…
