Structural and magnetic properties with reversible magnetocaloric effect in PrSr_1–xPb_xMn₂O₆ (0.1 ≤ x ≤ 0.3) double perovskite manganite structures

Magnetic behavior, Griffiths phase and magneto-transport study in 3d based nano-crystalline double perovskite Pr2CoMnO6

“…Double perovskites with the general formula A 2 BB ′ O 6 (where the B and B ′ sites are occupied by transition metal ions and the A site is occupied by rare earth ions) have been revitalized due to its varied magnetic and electrical properties and its importance for potential application in information technology and different spintronics applications like spin-based sensors, multiplestate memory elements, relaxor ferroelectricity, magnetodielectric capacitors etc. [1][2][3][4][5][6][7][8][9][10] In particular, 3d based double perovskite compounds form fascinating class of material, and have receive great attention of researchers due to their unusual physical properties. For instance, high temperature ferromagnetic La 2 NiMnO 6 is a potential candidate for Piltier cooler.…”

Role of nickel doping on magnetocaloric properties of La0.7Sr0.3Mn1−xNixO3 manganites

“…8, it can be said that the samples have a second-order transition due to their positive slope in TC region. Materials showing second-order magnetic phase transition are more advantageous than those with first-order transition because they have low thermal and magnetic hysteresis, which is of great importance for technological requirements [48]. It is seen from the Arrott curves of each sample at its transition temperature that the curves pass through the origin.…”

Magnetic and magnetocaloric properties of 0.5La0.7Ca0.2Sr0.1MnO3/0.5La0.7Te0.3MnO3 composite

“…However, some factors such as the cost of Gd and hard preparing methods limit usage of Gd and Gd-based alloys [3]. Because of these limitations, many researchers have been tending toward perovskite manganites [9][10][11][12][13] symbolized with the general formula R1−xAxMnO3 (R=rare earth elements, A: monovalent and divalent elements) which have advantages such as simple preparation methods, chemical stability and low cost [14]. The ∆ values which are comparable with Gd have been reported for doped manganites [15][16][17][18].…”
