Pressure-dependent "Insulator-Metal-Insulator" Behavior in Sr-doped LaNiO
Mingyu Xu, Shuyuan Huyan, Haozhe Wang +7
Recently, superconductivity at high temperatures has been observed in bulk LaNiO under high pressure. However, the attainment of high-purity LaNiO s…
Direct entropy determination and application to artificial spin ice
Paul E. Lammert, Xianglin Ki, Jie Li +4
From thermodynamic origins, the concept of entropy has expanded to a range of statistical measures of uncertainty, which may still be thermodynamically significant. However, labora…
Coexistence of Weak Ferromagnetism and Ferroelectricity in the High Pressure LiNbO3-type Phase of FeTiO3
T. Varga, A. Kumar, E. Vlahos +11
We report the magnetic and electrical characteristics of a polycrystalline specimen of FeTiO3 synthesized at high pressure that is isostructural with acentric LiNbO3 (LBO). Piezore…
Energy minimization and AC demagnetization in a nanomagnet array
X. Ke, J. Li, C. Nisoli +5
We study AC demagnetization in frustrated arrays of single-domain ferromagnetic islands, exhaustively resolving every (Ising-like) magnetic degree of freedom in the systems. Althou…
Structure and magnetic properties of the Ho2Ge2O7 pyrogermanate
E. Morosan, J. A. Fleitman, Q. Huang +7
We report the anisotropic magnetic properties of Ho2Ge2O7 determined from dc and ac magnetization, specific heat and powder neutron diffraction experiments. The magnetic lanthanide…
Spin ice behavior in Dy2Sn2-xSbxO7+x/2 and Dy2NbScO7
X. Ke, B. G. Ueland, D. V. West +3
We report the magnetic and thermal properties of Dy2Sn2-xSbxO7+x/2, x = 0, 0.25, and 0.5, and Dy2NbScO7. We find evidence for Ising-like single ion ground states in the Dy2Sn2-xSbx…
