“…It is believed that electron-electron correlation interaction can also give rise to resistance upturn that includes an additional term ∞ T 1/2 in the resistance expression. [47,50,51] Therefore, we modified the equation for resistance in the metallic region as R FM = R 0 +AT 2 +BT 5 -CT 1/2 and fitted our resistance in the whole temperature range. Here, C is the electron-electron correlation coefficient.…”

Phase separation in manganites leads to unique magnetic and electronic properties. 50% Ca‐doped LaMnO3 (LCMO), at the boundary of ferromagnetic (FM) and antiferromagnetic (AFM) states in La1‐xCaxMnO3 (0 ≤ x ≤ 1), is an ideal system to study phase separation behavior. The investigation reveals the effect of a 5d‐metal perovskite SrIrO3 (SIO) on the phase separation, magnetic, and magnetoresistance (MR) properties of LCMO. Single‐layer and bilayer LCMO films, both appear purely ferromagnetic along the in‐plane (IP) magnetic field direction, but show the tendency of temperature‐dependent ferromagnetic and antiferromagnetic or charge‐ordered (CO) phase separation with the out‐of‐plane (OOP) applied field. The MR, and colossal magnetoresistance (CMR), observed in LCMO/SIO bilayers are two orders and an order of magnitude (in %) larger, respectively than that in the single‐layer film. The coexistence of FM and AFM/CO phases is responsible for the CMR and MR enhancement in the LCMO/SIO bilayer, pointing toward the importance of the phase separation and competition of both the individual materials in enhancing their magnetic and electronic properties.

“…In order to gain more in-depth into the magnetic properties within the paramagnetic (PM) region, a graph illustrating the inverse of 𝜒𝜒𝜒𝜒 ′ plotted against temperature (T) was generated, as depicted in Figure 3 Under a 0.8 T magnetic field, however, the resistivity slightly reduced supported by the graph of log ρ versus temperature (in the inset of Figure 4), resulting in the magnetoresistance (MR) effect. The MR effect which calculated using equation MR (%) =(ρ(0,T)-ρ(H,T))/ρ(0,T) ×100% , where ρ(0,T) and ρ(H,T) represent the resistivity for 0 T and 0.8 T fields [25][26][27]. The MR % is high at low temperatures, as shown in Figure 5, indicating the extrinsic mechanism of MR effect.…”

The effects of partial substitution of Fe at the Mn site on structural, magnetic, and electrical properties of monovalent doped Pr0.75Na0.05K0.20Mn0.95Fe0.05O3 manganite prepared by the solid-state method were investigated. X-ray Diffractometer, AC Susceptibility, and four point probe measurements were used to characterize the structural, magnetic, and electrical properties. The sample crystallized in an orthorhombic structure with a Pnma space group. The sample exhibited ferromagnetic (FM) to paramagnetic (PM) transition behaviour with Curie Temperature, TC value of 121.5 K. From the Resistivity versus temperature analysis, the sample exhibited insulating behaviourover entire temperature from 30 K - 300 K. Fe substitution exhibited high magnetoresistance (MR %) value at low temperature region, indicating the extrinsic mechanism of MR effect.

“…Their presence has a significant appeal to researchers and technicians, prompting them to do depth studies. Some intriguing phenomena can be explored, such as microwave absorber properties, magnetostriction, magnetoresistance, [12][13][14][15] magnetocaloric effect, 1,4,16,17 multiferroic properties, 7 and others. One of the phenomena that has been intensively developed for the application of MRT is the magnetocaloric effect (MCE).…”
