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…
Magnetic resonance study of rare-earth titanates
Ana Najev, Sajna Hameed, Alexey Alfonsov +5
We present a nuclear magnetic resonance (NMR) and electron spin resonance (ESR) study of rare-earth titanates derived from the spin-1/2 Mott insulator YTiO. Measurements of sin…
Growth and characterization of large (Y,La)TiO and (Y,Ca)TiO single crystals
S. Hameed, J. Joe, L. R. Thoutam +12
The Mott-insulating rare-earth titanates (RTiO, R being a rare-earth ion) are an important class of materials that encompasses interesting spin-orbital phases as well as ferrom…
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…
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…
Nature of the ferromagnetic-antiferromagnetic transition in YLaTiO
S. Hameed, S. El-Khatib, K. P. Olson +18
We explore the magnetically-ordered ground state of the isovalently-substituted Mott-insulator YLaTiO for 0.3 via single crystal growth, magnetometry…
Ferroelectric quantum criticality and enhanced superconductivity in plastically deformed strontium titanate
S. Hameed, D. Pelc, Z. W. Anderson +13
The properties of quantum materials are commonly tuned using experimental variables such as pressure, magnetic field and doping. Here we explore a different approach: irreversible,…
