The strengthening of reentrant pinning by collective interactions in the peak effect
J. Lefebvre, M. Hilke, Z. Altounian
Since it was first observed about 40 years ago [1], the peak effect has been the subject of numerous research mainly impelled by the desire to determine its exact mechanisms. Despi…
Superconductivity and short range order in metallic glasses FeNiZr
J. Lefebvre, M. Hilke, Z. Altounian
In amorphous superconductors, superconducting and vortex pinning properties are strongly linked to the absence of long range order. Consequently, superconductivity and vortex phase…
Local magnetization fluctuations in superconducting glasses resolved by Hall sensors
J. Lefebvre, M. Hilke, Z. Altounian +2
We report on magnetization measurements performed on a series of FeNiZr superconducting metallic glasses with using the Hall effect of a nearby…
Transverse depinning in weakly-pinned vortices
J. Lefebvre, M. Hilke, Z. Altounian
We present experiments on weakly-pinned vortices, which exhibit a large critical transverse depinning force. These results are obtained in the superconducting metallic glasses Fe$_…
Origin and tuning of the magnetocaloric effect for the magnetic refrigerant MnFe(P1-xGex)
Danmin Liu, Ming Yue Jiuxing Zhang, T. M. McQueen +8
Neutron diffraction and magnetization measurements of the magneto refrigerant Mn1+yFe1-yP1-xGex reveal that the ferromagnetic and paramagnetic phases correspond to two very distinc…
Experimental evidence for a large critical transverse depinning force in weakly-pinned vortices
J. Lefebvre, M. Hilke, Z. Altounian
We present experimental evidence for the existence of a large critical transverse depinning force. These results are obtained in the weakly-pinned superconducting metal glasses Fe$…
