Exotic magnetism in perovskite KOsO3
Jie Chen, Hongze Li, Javier Gainza +10
A new perovskite KOsO3 has been stabilized under high-pressure and high temperature conditions. It is cubic at 500 K (Pm-3m) and undergoes subsequent phase transitions to tetragona…
Low thermal conductivity in La-filled cobalt antimonide skutterudites with an inhomogeneous filling factor prepared under high-pressure conditions
F. Serrano-Sánchez, J. Prado-Gonjal, N. M. Nemes +7
La-filled skutterudites LaxCo4Sb12 (x : 0.25 and 0.5) have been synthesized and sintered in one step under high-pressure conditions at 3.5 GPa in a piston-cylinder hydrostatic pres…
Experimental evidence for stochastic switching of supercooled phases
Devendra Kumar, K. P. Rajeev, J. A. Alonso +1
First-order phase transition in a highly correlated electron system can manifest as a dynamic phenomenon. The presence of multiple domains of the coexisting phases average out the…
Spin canted magnetism, decoupling of charge and spin ordering in NdNiO
Devendra Kumar, K. P. Rajeev, J. A. Alonso +1
We report detailed magnetization measurements on the perovskite oxide NdNiO. This system has a first order metal-insulator (M-I) transition at about 200 K which is associated w…
Evidence of kinetically arrested supercooled phases in the pervoskite oxide NdNiO
Devendra Kumar, K. P. Rajeev, J. A. Alonso +1
We report the time and temperature dependent response of thermopower in the non-magnetic perovskite oxide NdNiO. We find that on cooling below the metal-insulator transition te…
Slow Dynamics in Hard Condensed Matter: A Case Study of the Phase Separating System NdNiO
Devendra Kumar, K. P. Rajeev, J. A. Alonso +1
We report the time dependent response of electrical resistivity in the non-magnetic perovskite oxide NdNiO in its phase separated state and provide a physical explanation of th…
Crossover in the nature of the metallic phases in the perovskite-type RNiO_3
K. Okazaki, T. Mizokawa, A. Fujimori +3
We have measured the photoemission spectra of NdSmNiO, where the metal-insulator transition and the Néel ordering occur at the same temperature for $x \lesssim…
