Intra-wire coupling in segmented Ni/Cu nanowires deposited by electrodeposition
Philip Sergelius, Ji Lee, Olivier Fruchart +18
Segmented magnetic nanowires are a promising route for the development of three dimensional data storage techniques. Such devices require a control of the coercive field and the co…
Electronic structure and properties of (TiZrNbCu)_1-xNi_x high entropy amorphous alloys
Katica Biljaković, György Remenyi, Ignacio A. Figueroa +6
A comprehensive study of selected properties of four (TiZrNbCu)_1-xNi_x (x \le 0.25) amorphous high entropy alloys (a-HEA) has been performed. The samples were ribbons about 20 \mu…
Glass phase and other multiple liquid-to-liquid transitions resulting from two liquid phase competition
Robert F. Tournier
Melt supercooling leads to glass formation. Liquid-to-liquid phase transitions are observed depending on thermal paths. Viscosity, density and surface tension thermal dependences m…
Relaxation time spectrum of low-energy excitations in one- and two-dimensional materials with charge or spin density waves
S. Sahling, G. Remenyi, J. E. Lorenzo +3
The long-time thermal relaxation of (TMTTF)Br, SrCuO and SrCaCuO single crystals at temperatures below 1 K and magnetic field up t…
On entropy change measurements around first order phase transitions in caloric materials
Luana Caron, Nguyen Ba Doan, Laurent Ranno
In this work we discuss the measurement protocols for indirect determination of the isothermal entropy change associated with first order phase transitions in caloric materials. Th…
Double Vibronic process in the quantum spin ice candidate TbTiO revealed by terahertz spectroscopy
E. Constable, R. Ballou, J. Robert +8
The origin of quantum fluctuations responsible for the spin liquid state in TbTiO has remained a long standing problem. By synchrotron-based terahertz measurements, we…
