Magnetism and infrared magnetotransmission of Nd0.5Sr0.5MnO3 manganite in nanostate

A new approach for crystallization of copper(ii) oxide hollow nanostructures with superior catalytic and magnetic response

“…Therefore, the magnetic system prefers to remain in the socalled single domain state (also termed as elongated grains or mesocrystals) and show a hysteresis loop that is quite different from that observed in corresponding bulk systems. 27,[56][57][58][59] The temperature-dependent variation of the magnetic parameters in hollow CuO nanostructures is given in Fig. 8 (b and c).…”

The effect of the gelation temperature on the structural, magnetic and magnetocaloric properties of perovskite nanoparticles manufactured using the sol–gel method

“…In order to check whether LS1, LS2 and LS3 exhibit spin-glass behavior, Mydosh parameter Ω = Δ T f / ( T f Δlog( f )) needs to be calculated, T f the temperature of the peak in ac susceptibility versus temperature also called the freezing temperature and f is the frequency. 25,26 Ω is found to be 0.005 for LS1 and LS2, and 0.006 for LS3. It is common that Ω for spin glass systems varies between 0.004 to 0.018, 27 which is the case for LS1, LS2 and LS3 samples.…”

X-ray spectra and charge states of cations in nanostructured manganites La0.5Ca0.5MnO3 and Nd0.5Sr0.5MnO3

“…A maximum in the size distribution particles for the powder after the grinding for 8 h was ∼75 nm. SEM images of the nanostructured Nd 0.5 Sr 0.5 MnO 3 powder are presented in [8,9]. X-ray absorption spectra of nanostructured manganites were measured in the surface-sensitive total electron yield mode on a Russian-German line of the BESSY-II storage ring (Berlin) and in the bulk-sensitive fluorescence yield mode on a I511-3 line of the MAX II storage ring (Lund).…”
