Effect of random antiferromagnetic exchange on the spin waves in a three-dimensional Heisenberg ferromagnet
S. Hameed, Z. Wang, D. M. Gautreau +12
Neutron scattering is used to study spin waves in the three-dimensional Heisenberg ferromagnet YTiO, with spin-spin exchange disorder introduced La-substitution at the Y…
Uniaxial strain control of bulk ferromagnetism in rare-earth titanates
Ana Najev, Sajna Hameed, Dominique M. Gautreau +7
The perovskite rare-earth titanates are model Mott insulators with magnetic ground states that are very sensitive to structural distortions. These distortions couple strongly to th…
Strain-tunable metamagnetic critical endpoint in Mott insulating rare-earth titanates
Zhentao Wang, Dominique Gautreau, Turan Birol +1
Rare-earth titanates are Mott insulators whose magnetic ground state -- antiferromagnetic (AFM) or ferromagnetic (FM) -- can be tuned by the radius of the rare-earth element. Here,…
Two-component electronic phase separation in the doped Mott insulator YCaTiO
S. Hameed, J. Joe, D. M. Gautreau +3
One of the major puzzles in condensed matter physics has been the observation of a Mott-insulating state away from half-filling. The filling-controlled Mott insulator-metal transit…
Coexistence and interaction of spinons and magnons in an antiferromagnet with alternating antiferromagnetic and ferromagnetic quantum spin chains
H. Zhang, Z. Zhao, D. Gautreau +10
In conventional quasi-one-dimensional antiferromagnets with quantum spins, magnetic excitations are carried by either magnons or spinons in different energy regimes: they do not co…
