Exploring the energy landscape of resistive switching in antiferromagnetic Sr(3)Ir(2)O(7)
Morgan Williamson, Shida Shen, Gang Cao +3
We study the resistive switching triggered by an applied electrical bias in antiferromagnetic Mott insulator Sr(3)Ir(2)O(7). The switching was previously associated with an electri…
Synthesis of monoclinic IrTe2 under high pressure and its physical properties
X. Li, J. -Q. Yan, D. J. Singh +2
In a pressure-temperature (P-T) diagram for synthesizing IrTe2 compounds, the well-studied trigonal (H) phase with the CdI2-type structure is stable at low pressures. The supercond…
Suppression of the Magnetic Phase Transition in Manganites Close to the Metal-Insulator Crossover
F. Rivadulla, J. Rivas, J. B. Goodenough
We report the suppression of the magnetic phase transition in La1-xCaxMnO3 close to the localized-to-itinerant electronic transition, i.e. at x = 0.2 and x = 0.5. A new crossover t…
Chemical, Structural, and Transport Properties of Na1-xCoO2
F. Rivadulla, J. S. Zhou, J. B. Goodenough
We report measurement of room-temperature compressibility, thermal expansion, thermoelectric power a(T) at various pressures P < 20 kbar, basal-plane resistivity rab (T), magnetic…
Phase Competition in Ln0.5a0.5mno3 Perovskites
F. Rivadulla, E. Winkler, J. -S. Zhou +1
Single crystals of the systems Pr0.5(Ca1-xSrx)0.5MnO3, (Pr1-yYy)0.5(Ca1-xSrx)0.5MnO3, and Sm0.5Sr0.5MnO3 were grown to provide a series of samples with fixed ratio Mn(III)/Mn(IV)=1…
Structural transformation induced by magnetic field and colossal magnetoresistance response above 313 K in MnAs
J. Mira, F. Rivadulla, J. Rivas +5
MnAs exhibits a first-order phase transition from a ferromagnetic, high-spin metal NiAs-type hexagonal phase to a paramagnetic, lower-spin insulator MnP-type orthorhombic phase at…
