Temperature oscillations of magnetization observed in nanofluid ferromagnetic graphite
S. Sergeenkov, N. S. Souza, C. Speglich +5
We report on unusual magnetic properties observed in the nanofluid room-temperature ferromagnetic graphite (with an average particle size of l=10nm). More precisely, the measured m…
Manifestation of finite temperature size effects in nanogranular magnetic graphite
S. Sergeenkov, N. S. Souza, C. Speglich +5
In addition to the double phase transition (with the Curie temperatures T_C=300K and T_{Ct}=144K), a low-temperature anomaly in the dependence of the magnetization is observed in t…
Unusually strong coherent response from grain-boundary Josephson network in polycrystalline Pr_{x}Y_{1-x}Ba_2Cu_3O_7
V. A. G. Rivera, S. Sergeenkov, C. Stari +4
By applying a highly sensitive homemade AC susceptibility technique to Pr_{x}Y_{1-x}Ba_2Cu_3O_7 polycrystals (with x=0.0, 0.1 and 0.3), we observed very sharp Fraunhofer type low-f…
