Magnetic properties of MoS 2 nanotubes doped with lithium
2003
DC magnetization measurements of lithium-doped molybdenum sulfide nanotubes (LixMoS2, 2.2 10 kOe, the nonlinear part in H<5 kOe with saturation at approximately 10 kOe can be observed. This suggests a formation of ferromagnetic clusters even at room temperature. No magnetic phase transition between 2 and 300 K has been detected.
Unusual Magnetic State in Lithium-DopedMoS2Nanotubes
2003
We report on the very peculiar magnetic properties of an ensemble of very weakly coupled lithium-doped MoS2 nanotubes. The magnetic susceptibility chi of the system is nearly 3 orders of magnitude greater than in typical Pauli metals, yet there is no evidence for any instability which would alleviate this highly frustrated state. Instead, the material exhibits peculiar paramagnetic stability down to very low temperatures, with no evidence of a quantum critical point as T-->0 in spite of clear evidence for strongly correlated electron behavior. The exceptionally weak intertube interactions appear to lead to a realization of a near-ideal one-dimensional state in which fluctuations prevent the…
Themes of nanoscience for the introductory physics course
2009
We present three experimental themes and one discussion theme that proved to be suitable for introducing nanoscience through topics that can be integrated into the existing introductory physics or teacher training courses. The experimental themes include two teaching models of an atomic force microscope (AFM) and an experiment with an elastic optical grating. They are all based on simple experiments that give also quantitative results and can be explained using basic physics theory.
