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…
High-pressure single-crystal neutron scattering study of magnetic and Fe vacancy orders in (Tl,Rb)2Fe4Se5 superconductor
Feng Ye, Wei Bao, Songxue Chi +7
The magnetic and iron vacancy orders in superconducting (Tl,Rb)2Fe4Se5 single-crystals are investigated by using a high-pressure neutron diffraction technique. Similar to the tempe…
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…
