“…Hence, nonlinear ac susceptibility χ n has become an efficient experimental method for distinguishing the different magnetic orderings [14], [24][25][26][27]. Earlier, the systematic doping-concentration-dependent evolution of the frustrated magnetic phase was reported for low bandwidth manganite Nd 1−x Ca x MnO 3 [28,29] and Nd 1−x Sr x MnO 3 [27,30], though for PCMO most ac-susceptibility studies concentrated on the higher hole doping regime in the vicinity of the CO phase [30][31][32][33]. Also the effect of the dc magnetic field on the domain wall motion and the non-linear ac susceptibility for the low-hole doping range of PCMO has not been studied.…”

The complex linear and nonlinear ac susceptibility have been thoroughly investigated in the low bandwidth manganite compound Pr(1-x)Ca(x)MnO3 (PCMO) for the doping range x = 0.0-0.3 with and without a superimposed background dc field. The dynamical ac response shows substantial differences between the samples. The sample with x = 0.1 is found to have two separate magnetic transition peaks, compared to the single transitions in the samples x = 0.0 and x = 0.2. The nonlinear ac susceptibility measurements were compared between samples, which confirmed that these transition peaks are similar in nature and from the same magnetic origin. Additionally, for sample x = 0.3 a complex transition peak structure with overlapping transition peaks was found. This kind of evolution of the magnetic phases as a function of the Ca concentration is believed to rise from coexisting antiferromagnetic (AFM) and ferromagnetic (FM) orderings, where the Ca concentration controls the amount of FM clusters in the sample. The spin glass characteristics of these complex phase-separated magnetic regimes showed similarities and contradictions with conventional spin glasses, which indicates that this cluster glass behavior arises from the frustration between competing AFM and FM clusters having different magnetic exchange interaction.

“…The reported Pr 0.5 Ca 0.5 MnO 3 in the nano range also shows orthorhombic phase [34]. Nd 1-x Ca x MnO 3 (0 ≤ x ≤ 0.6) reported as orthorhombic phase, [35,36] and Nd 0.5 Ca 0.5 MnO 3 nanocrystalline also shows the orthorhombic structure [37]. In the La 1-x Ca x MnO 3 system, it has been reported the coexistence of O'-and O-orthorhombic structures in the range 0.1 ≤ x ≤ 0.15 [38].…”

The perovskite with R 1−x A x MnO 3 (R = rare-earth and A = divalent metals) formula has worldwide attention due to its fascinating electrical and magnetic properties. A-site doped manganite perovskite oxides were broadly investigated based on theoretical and experimental point-of-view due to interesting phenomenon such as charge ordering, orbital ordering, colossal magnetoresistance, order-disorder transition, phase separation scenario, etc. Such kind of manganite system has two types of transitions as an insulator to metal transition and paramagnetic to ferromagnetic transition. The significance of perovskite materials and their electronic, magnetic or structural phase transition temperatures were analyzed with different experimental results.
