In this work we address the interplay between two phenomena which are signatures of the out-of-equilibrium state in phase separated manganites: irreversibility against thermal cycling and aging/rejuvenation process. The ...

It was already shown that a qualitative understanding of the pressure effects on the ferromagnetic transition temperature (Tc) of the perovskite manganites (AMnO3) results from the variation of the geometric factors that ...

We have measured the electrical resistance of micrometric to nanometric powders of the La5 /8-y PryCa3 /8 MnO3 (LPCMO with y=0.3) manganite for hydrostatic pressures up to 4 kbar. By applying different final thermal ...

Yttrium manganite (YMnO3) is a multiferroic material, which means that it exhibits both ferromagnetic and ferroelectric properties, so making it interesting for a variety of technological applications. In this work, ...

We investigate a series of manganese oxides, the La0.225Pr0.4(Ca1−xSrx)0.375MnO3 system. The x=0 sample is a prototype compound for the study of phase separation in manganites, where ferromagnetic and charge ordered ...

We performed high-pressure experiments in La0.8Ca0.2-xSr xMnO3 (LCSMO)(0≤ x ≤ 0.2) ceramic samples in order to analyze the validity of the well-known relation between the A-cation mean ionic radius ((ra)) and the Curie ...

We studied La0.325Pr0.300Ca0.375MnO3-Ag memristive interfaces. We present a pulsing/measuring protocol capable of registering both quasi-static i-v data and non-volatile remnant resistance. This protocol allowed distinguishing ...

We have studied the irreversibility of the magnetization induced by thermal cycles in La0.5Ca0.5MnO3 manganites, which present a low temperature state characterized by the coexistence of phases. The effect is evidenced by ...
