Magnetic field-dependent dielectric constant in La2/3Ca1/3MnO3
J. Rivas, J. Mira, B. Rivas-Murias +4
We report a rather high dependence of the dielectric permittivity on the magnetic field in La2/3Ca1/3MnO3. The variation is maximum at around 270 K, little above the Curie temperat…

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…
