Magnetocaloric properties in Ln0.67Ba0.33Mn1−xFexO3 (Ln=La or Pr) manganites

Effect of Al substitution on magnetocaloric effect in La0.57Nd0.1Sr0.33Mn1−xAlxO3 (0.0≤x≤0.30) polycrystalline near room temperature

“…For the Al doped sample LNSMAO, RCP with H = 10 kOe increases from 23 J/kg for x = 0 to 68 J/kg for x = 0.3. Nearly similar RCP values have been reported for La 0.67 Ba 0.33 Mn 1−x Fe x O 3 [39] and La 0.7 Sr 0.3 Mn 1−x Al x O 3 [28]. Refrigerants with a wide working temperature span and high RCP are in fact very beneficial to magnetic cooling applications.…”

Effect of Fe doping on properties of Pr0.67Ba0.33Mn1-xFexO3perovskites

“…The effect of trivalent magnetic (Fe 3+ ) or tetravalent non-magnetic (Ti 4+ ) substitution for Mn on magnetic and electrical properties [7][8][9] appears quite similar in both systems and eliminates the ferromagnetic/metallic (FM/M) and paramagnetic/ insulator (PM/I) transitions in these systems. More recently we have shown that the Pr 0.67 Ba 0.33 Mn 1-x Fe x O 3 iron doped systems presents very interesting magnetocaloric properties [10]. In this paper we report in more details its structural, magnetic and electrical properties that appear quite similar to previous Ba-doped studied system.…”
