From antiferromagnetic insulator to correlated metal in pressurized and doped LaMnPO
Jack Simonson,Zhiping Yin,Zhiping Yin,M. Pezzoli,M. Pezzoli,Jiangang Guo,Jian Liu,Kirk Post,A. Efimenko,N. Hollmann,Zhiwei Hu,Hong-Ji Lin,Chunxia Chen,C. Marques,V. Leyva,G. J. Smith,Jeffrey W. Lynn,Liling Sun,Gabriel Kotliar,Dimitri Basov,Liu Hao Tjeng,Meigan Aronson,Meigan Aronson +22 more
TL;DR: Electronic structure calculations and X-ray diffraction measurements presented here challenge long held beliefs, finding that only modest pressures are required to transform LaMnPO, isostructural to superconducting host LaFeAsO, from an antiferromagnetic insulator to a metallic antiferrosagnet, where the Mn moment vanishes in a second pressure-driven transition.
Journal ArticleDOI
CaMn2Sb2: Spin waves on a frustrated antiferromagnetic honeycomb lattice
Daniel McNally,Jack Simonson,J. J. Kistner-Morris,G. J. Smith,J. E. Hassinger,Lisa DeBeer-Schmitt,Alexander I. Kolesnikov,Igor Zaliznyak,Meigan Aronson,Meigan Aronson +9 more
TL;DR: In this article, inelastic neutron scattering measurements of the antiferromagnetic insulator (a compound that lies very close to the mean field tricritical point on the honeycomb lattice, where the N\'eel phase and two different spiral phases coexist.
Journal ArticleDOI
Magnetic and structural phase diagram of CaMn2Sb2
Jack Simonson,G. J. Smith,Kirk Post,M. Pezzoli,M. Pezzoli,J. J. Kistner-Morris,Daniel McNally,J. E. Hassinger,Christie Nelson,Gabriel Kotliar,Dimitri Basov,Meigan Aronson,Meigan Aronson +12 more
TL;DR: In this paper, an antiferromagnetic insulator that exhibits weak ferromagnetic order above the N ¼ eel temperature was found to exhibit the signature of magnetic polarons.
Journal ArticleDOI
Gap states in insulating LaMnPO 1 − x F x ( x = 0 –0.3)
Jack Simonson,Kirk Post,C. Marques,G. J. Smith,Omar Khatib,Dimitri Basov,Meigan Aronson,Meigan Aronson +7 more
TL;DR: In this paper, infrared and electrical resistivity measurements reveal that single crystals of LaMnPO are insulating at low temperatures, described well by variable range hopping conduction between these localized gap states.
Journal ArticleDOI
Origin of the charge gap in LaMnPO
Daniel McNally,Jack Simonson,Kirk Post,Zhiping Yin,M. Pezzoli,M. Pezzoli,G. J. Smith,V. Leyva,C. Marques,Lisa DeBeer-Schmitt,Alexander I. Kolesnikov,Yang Zhao,Jeffrey W. Lynn,Dimitri Basov,Gabriel Kotliar,Meigan Aronson,Meigan Aronson +16 more
TL;DR: In this article, high temperature inelastic neutron scattering and magnetic susceptibility measurements of the antiferromagnetic insulator LaMnPO that are consistent with the presence of two-dimensional magnetic correlations up to a temperature
