Atypical magnetic behavior in the incommensurate hybrid perovskite
Breogán Pato-Doldán, Laura Caňadillas-Delgado, L. Claudia Gómez-Aguirre +4
A plethora of temperature induced phase transitions have been observed in compounds, where M is Co(II) or Ni(II). Among them, the nickel compound exhibits a…
Coupled magnetic and electric hysteresis in the multiferroic double perovskite Lu2MnCoO6
Vivien S. Zapf, B. G. Ueland, Mark Laver +10
We investigate a magnetic hysteresis loop with a remanent moment that couples to electric polarization to create coupled hysteretic multiferroic behavior in Lu2MnCoO6. Measurements…
Power-law decay in first-order relaxation processes
A. Fondado, J. Mira, J. Rivas
Starting from a simple definition of stationary regime in first-order relaxation processes, we obtain that experimental results are to be fitted to a power-law when approaching the…
Dielectric response of the charge-ordered two-dimensional nickelate La1.5Sr0.5NiO4
J. Rivas, B. Rivas-Murias, A. Fondado +2
We are reporting the dielectric response of La1.5Sr0.5NiO4, a system that presents a charge-ordered state above room temperature and a rearrangement of its charge-order pattern in…
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…
First order transition and phase separation in pyrochlores with colossal-magnetoresistance
P. Velasco, J. Mira, F. Guinea +4
TlMnO pyrochlores present colossal magnetoresistance (CMR) around the long range ferromagnetic ordering temperature (T). The character of this magnetic phas…
