Fabrication and physical properties of stable room temperature bulk ferromagnetic graphite
H. Pardo, R. Faccio, A. W. Mombru +2
The search for macroscopic magnetic ordering phenomena in organic materials, in particular in pure graphite, has been one of the more exciting scientific activities working in the…
Stable room temperature magnetic graphite
H. Pardo, F. M. Araujo-Moreira, R. Faccio +6
Carbon materials are attracting increasing attention due to the novelty of the associated physical properties and the potential applications in high-tech devices. The possibility t…
Comparative study of specific heat measurements in LaMnO3, La1.35Sr1.65Mn2O7, La1.5Sr0.5NiO4 and La1.5Sr0.5CoO4
J. Lopez, O. F. de Lima, C. A. Cardoso +2
We present the temperature dependence of the specific heat, without external magnetic field and with H= 9 T, for LaMnO3, La1.35Sr1.65Mn2O7, La1.5Sr0.5NiO4 and La1.5Sr0.5CoO4 single…
Spin Glass Behavior in the Ru-1222 and Ru-1212 rutheno-cuprate families: a comparative study
C. A. Cardoso, F. M. Araujo-Moreira, V. P. S. Awana +3
Strong evidences of a spin glass phase on polycrystalline RuSr2Ln1.5Ce0.5Cu2O10-x (LnRu-1222, Ln = Y, Ho and Dy) is provided by ac susceptibility and dc magnetization measurements.…
High temperature specific heat and magnetic measurements in Nd0.5Sr0.5MnO3 and R0.5Ca0.5MnO3 (R=Nd, Sm, Dy and Ho) samples
J. Lopez, O. F. de Lima
We have made a magnetic characterization of Nd0.5Sr0.5MnO3, Nd0.5Ca0.5MnO3, Sm0.5Ca0.5MnO3, Dy0.5Ca0.5MnO3 and Ho0.5Ca0.5MnO3 polycrystalline samples. Ferromagnetic, antiferromagne…
Studies on the Anisotropic Properties of MgB2
O. F. de Lima
This paper presents a brief review on the reported anisotropic properties of MgB2, in the superconducting state (e.g. upper critical field Hc2, field penetration depth, coherence l…
