Grain size modification in the magnetocaloric and non-magnetocaloric transitions in La0.5Ca0.5MnO3 probed by direct and indirect methods
M. Quintero, S. Passanante, I. Irurzub +2
The influence of the grain size in the magnetic properties of phase separated manganites is an important issue evidenced more than a decade ago. The formation of long range ordered…
Revealing polarons with high pressure on low electron-doped manganites
G. Garbarino, C. Acha, D. Vega +5
Pressure sensitivity (up to 1 GPa) of the electrical resistivity and of the ac susceptibility was measured for low electron doping levels of CaYMnO (CYMO) and of Ca…
Low temperature irreversibility induced by thermal cycles on two prototypical phase separated manganites
J. Sacanell, M. Quintero, J. Curiale +8
We have studied the effect of irreversibility induced by repeated thermal cycles on the electric transport and magnetization of polycrystalline samples of La0.5Ca0.5MnO3 and La0.32…
High temperature susceptibility in electron doped Ca1-xYxMnO3: Double Exchange vs Superexchange
H. Aliaga, M. T. Causa, M. Tovar +6
We present a study of the magnetic properties of the electron doped manganites Ca1-xYxMnO3 (for 0<=x<=0.25) in the paramagnetic regime. For the less doped samples (x<=0.1) the magn…
Persistent magnetoresistive memory in phase separated manganites
P. Levy, F. Parisi, J. Sacanell +10
We have studied magnetic and transport properties on different manganese oxide based compounds exhibiting phase separation: polycrystalline La5/8-yPryCa3/8MnO3 (y=0.3) and La1/2Ca1…
Novel dynamical effects and persistent memory in phase separated manganites
P. Levy, F. Parisi, L. Granja +2
The time dependent response of the magnetic and transport properties of Fe-doped phase separated (PS) manganite LaCaMnO is reported. The nontrivial coexistenc…
