Anomalous magnetic properties of multi-walled carbon nanotubes embedded with magnetic nanoparticles: Consistent with ultrahigh temperature superconductivity
Guo-meng Zhao, Jun Wang, Yang Ren +1
We report high-temperature (300-1120 K) magnetization data of Fe and Fe3O4 nanoparticles embedded in multi-walled carbon nanotubes. The magnetic impurity concerntations are precise…
High-temperature magnetic properties of noninteracting single-domain Fe3O4 nanoparticles
Jun Wang, Pieder Beeli, L. H. Meng +1
Magnetic measurements have been performed on 40-nm sphere-like Fe3O4 nanoparticles using a Quantum Design vibrating sample magnetometer. Coating Fe3O4 nanoparticles with SiO2 effec…
Giant magnetic moment enhancement of nickel nanoparticles embedded in multi-walled carbon nanotubes
Guo-meng Zhao, Pieder Beeli, Jun Wang +1
We report a giant magnetic moment enhancement of ferromagnetic nickel nanoparticles (11 nm) embedded in multi-walled carbon nanotubes. High-energy synchrotron x-ray diffraction exp…
Magnetic studies of multi-walled carbon nanotube mats: Evidence for the paramagnetic Meissner effect
Guo-meng Zhao, Pieder Beeli
We report magnetic measurements up to 1200 K on multi-walled carbon nanotube mats using Quantum Design vibrating sample magnetometer. Extensive magnetic data consistently show two…
Large oxygen-isotope shift above the quantum critical point of
John Mann, Pieder Beeli, Guo-meng Zhao
We have studied the oxygen-isotope effect on the superconducting transition temperature in overdoped YCaBaCuO with = 0.10, 0.20, and 0…
Very Unusual Magnetic Properties in Multi-walled Carbon Nanotube Mats
Guo-meng Zhao, Pieder Beeli
We report magnetic measurements up to 1100 K on a multi-walled carbon nanotube mat sample using a Quantum Design vibrating sample magnetometer. In an ultra-low field (H = -0.02 Oe)…
