Exceptional field dependence of antiferromagnetic magnons in LiFePO
J. Werner, C. Neef, C. Koo +3
Low-energy magnon excitations in magnetoelectric LiFePO have been investigated by high-frequency high-field electron spin resonance spectroscopy in magnetic fields up to B = 58…
Challenges in the crystal growth of Li2FeSiO4
Waldemar Hergett, Christoph Neef, Hans-Peter Meyer +1
The high-pressure optical floating-zone method enables single crystal growth of the Pmnb high-temperature phase of Li2FeSiO4. The influence of growth conditions on crystal quality,…
Antisite disorder in the battery material LiFePO
J. Werner, C. Neef, C. Koo +3
We report detailed magnetometry and high-frequency electron spin resonance (HF-ESR) measurements which allow detailed investigation on Li-Fe antisite disorder in single-crystalline…
Filled Carbon Nanotubes as Anode Materials for Lithium-Ion Batteries
Elisa Thauer, Alexander Ottmann, Philip Schneider +18
Downsizing well-established materials to the nanoscale is a key route to novel functionalities, in particular if different functionalities are merged in hybrid nanomaterials. Hybri…
Anisotropic ionic conductivity of LiMnFePO () single crystals
Christoph Neef, Elisa Thauer, Andreas Reiser +1
We report AC-impedance studies on a series of high-quality LiMnFePO single crystals with . Our results confirm quasi-one-dimensional transport in Li…
High-pressure optical floating-zone growth of Li2FeSiO4 single crystals
Waldemar Hergett, Christoph Neef, Hubert Wadepohl +5
We report the growth of mm-sized Pmnb-Li2FeSiO4 single crystals by means of the optical floating-zone method at high argon pressure and describe the conditions required for a stabl…
