Sb-5-mediated antiparallel Nd-Fe coupling in NdFeSb
S. Palazzese, Sh. Yamamoto, T. Kotte +15
We uncover the microscopic mechanism underlying the antiparallel Nd-Fe coupling in the intermetallic 4-3-5 compound NdFeSb by means of high-field x-ray magneti…
Direct High-Magnetic-Field Coupling to Stripe Order in a Cuprate Superconductor
Leonardo Martinelli, Izabela Biało, Jens Oppliger +47
Superconductivity in cuprates emerges out of a complex normal state that hosts density waves, pseudogap physics, and strange metal properties. Here, we access this normal state by…
Alfvén wave experiments with liquid rubidium in a pulsed magnetic field
Th. Gundrum, J. Forbriger, Th. Herrmannsdörfer +4
Magnetic fields are key ingredients for heating the solar corona to temperatures of several million Kelvin. A particularly important region with respect to this is the so-called ma…
Mode Conversion and Period Doubling at Plasma- Unity in an Alfvén-Wave Experiment with Liquid Rubidium
F. Stefani, J. Forbriger, Th. Gundrum +2
We report Alfvén-wave experiments with liquid rubidium at the Dresden High Magnetic Field Laboratory (HLD). Reaching up to 63 T, the pulsed magnetic field exceeds the critical valu…
Nonintrinsic origin of the magnetic-field-induced metal-insulator and electronic phase transitions in graphite
