Magnetic properties of TiCx/C nanocomposites

Synthesis and magnetic properties of highly dispersed tantalum carbide nanoparticles decorated on carbon spheres

“…[60][61][62] However, some reports are present on the magnetic properties of a TiC/C composite and/or an YBCO nanoparticle system where such anomalous ferromagnetic responses were observed even below T c . 63,64 Chen et al also reported the appearance of weak ferromagnetism and a spinglass like state in 40 nm sized nickel carbide. 65 In all the cases, the FM behavior of the composite sample is correlated with the various kinds of surface defects within the nanoparticles.…”

“…65 In all the cases, the FM behavior of the composite sample is correlated with the various kinds of surface defects within the nanoparticles. [63][64][65] If there is a sufficient net positive magnetization in the sample which can overcome the diamagnetism, the superconducting behavior might be suppressed. 64 In order to get a clearer view of the FM properties, the ZFC and FC measurements were performed at various temperatures and applied magnetic fields.…”

EPR, spectroscopic and photocatalytic properties of N-modified TiO2 prepared by different annealing and water-rinsing processes

“…Recently, ferromagnetically ordered states in titanium oxides as well in titanium carbide have been observed [14,43]. The two resonance lines (designated as line 1 and line 2) observed in low magnetic fields in sample [TiO 2 /400 C rinsed] which disappear below 50 K are assumed to arise from magnetic agglomerates (Fig.…”

Electrical and magnetic properties of silicon carbide composites with titanium and niobium carbide as sintering aids

“…It was published, that NbC exhibits superconductivity behavior near 11 K [26][27][28], TiC could be superconductive near 4 K [29] , so it was interesting to find out how NbC can influence the behavior of SiC/Ti-NbC composite. On this behalf magnetic measurements were carried out on the reference sample of SiC with no additives and also on the SiC with Ti-NbC addition.…”
