By substituting La by alkaline earth ions such as Sr and Ca, holes are effectively doped into thee. 0 and 0. Depending on the doping x , in manganites there are two dominant phases at low temperatures: a double-exchange ferromagnetic metal (FMM) and charge-ordered May 2, 2025 · Magnetoresistive and electrical response characteristics of hole-doped polycrystalline simple perovskite manganites La 0. The high-entropy samples (La 0. 2 Nd 0. [1–9]. For R La,as is well known, the A-type antiferromagnetic (AFM) phase appears with the C-type ordering of 3x2 r2 and 3y2 r2 orbitals [4]. 5), synthesized using the solid-state technique, show a change in the crystal structure from Pbn m to Jun 26, 2003 · The effect of ‘colossal magnetoresistance’ (CMR) in hole-doped manganites—an abnormal decrease of resistivity when a magnetic field is applied1—has attracted significant interest from Hence the general formula of a hole-doped manganite is RE 1-x AE x MnO 3 ( RE is a trivalent rare-earth ion such as La, Nd, Pr and AE is a divalent alkaline-earth ion such as Ca, Sr). 3 MnO 3 (x = 0. 6−x Ca x Sm 0. 2 Pr 0. 2 Eu 0. 2 ) 1− x Sr x MnO 3 (0 ≤ x ≤ 0. 1) Aug 13, 2014 · The hole-doped perovskite manganites Ln 1−x A x MnO 3 (Ln = rare earth, A = alkaline earth) have attracted great attention due to their fruitful electric and magnetic properties, such as the metal-insulator (M-I) transition, the paramagnetic (PM) to ferromagnetic (FM) phase transition, charge order (CO), the colossal magnetoresistance (CMR) effect, the magnetocaloric effect (MCE), etc. The parent compound of CMR manganites is undoped RMnO 3, where Rdenotes rare earth ions.
