Giant Magnetic Fluctuations at the Critical Endpoint in Insulating HoMnO3
Y. J. Choi, N. Lee, P. A. Sharma +5
Although abundant research has focused recently on the quantum criticality of itinerant magnets, critical phenomena of insulating magnets in the vicinity of critical endpoints (CEP…
In-plane and out-of-plane correlations in Ho(1-x)YxMnO3
Jagath Gunasekera, Owen P. Vajk, Yuan Wang +2
Strong magnetic-ferroelectric coupling in hexagonal HoMnO3 has been observed previously at spin reorientation temperature between P6'3cm' and the P6'3cm' magnetic phases. In contra…
Incident-energy and polarization dependent RIXS study of La2CuO4
L. Lu, J. N. Hancock, G. Chabot-Couture +7
We present a detailed Cu K-edge resonant inelastic X-ray scattering (RIXS) study of the Mott insulator La2CuO4 in the 1-7 eV energy transfer range. As initially found for the high-…
Magnetic inversion symmetry breaking and ferroelectricity in TbMnO3
M. Kenzelmann, A. B. Harris, S. Jonas +7
TbMnO3 is an orthorhombic insulator where incommensurate spin order for temperature T_N < 41K is accompanied by ferroelectric order for T < 28K. To understand this, we establish th…
Magnetic Order and Spin Dynamics in Ferroelectric HoMnO
O. P. Vajk, M. Kenzelmann, J. W. Lynn +2
Hexagonal HoMnO is a frustrated antiferromagnet (T=72 K) ferroelectric (T=875 K) in which these two order parameters are coupled. Our neutron measurements of the…
Charge-Transfer Excitations in the Model Superconductor HgBaCuO
L. Lu, X. Zhao, G. Chabot-Couture +9
We report a Cu -edge resonant inelastic x-ray scattering (RIXS) study of charge-transfer excitations in the 2-8 eV range in the structurally simple compound HgBaCuO…
