Název v původním jazyce

Metamagnetic transition of martensitic type in electron-doped manganites Ca1-xCexMnO3 (x=0.10, 0.12)

Popis výsledku v původním jazyce

Magnetic and electrical properties of electron-doped manganites Ca0.88Ce0.12MnO3 and Ca0.90Ce0.10MnO3 were studied in pulsed magnetic fields up to 60 T in the temperature range T = 1.5-260 K. Metamagnetic transition caused by the melting of the charge/orbital ordering and martensitic structural transition in a magnetic field was revealed. The transition is accompanied by a change in electrical resistivity of the sample by three orders. A magnetic phase diagram in the plane of the H-T was constructed. Higher values of the critical transition fields for the system Ca-1 xCexMnO3, compared to the known system Ca-1 xSmxMnO3 are explained by a narrower range of phase separation and a bigger difference between the Neel temperatures of the C and G-type antiferromagnetic phases, which originated from the difference between the valence of the Ce4+ and Sm3+ ions.
