Micromagnetic Simulations for Coercivity Improvement through Nano-Structuring of Rare-Earth Free L1-FeNi Magnets
Alexander Kovacs, Johann Fischbacher, Harald Oezelt +6
In this work we investigate the potential of tetragonal L1 ordered FeNi as candidate phase for rare earth free permanent magnets taking into account anisotropy values from rece…
Increased magnetocrystalline anisotropy in epitaxial Fe-Co-C thin films with spontaneous strain
Ludwig Reichel, George Giannopoulos, Sandra Kauffmann-Weiss +8
Rare earth free alloys are in focus of permanent magnet research since the accessibility of the elements needed for nowadays conventional magnets is limited. Tetragonally strained…
Nanostructured Melt-Spun Sm(Co,Fe,Zr,B)7:5 Alloys for High-Temperature Magnets
Sofoklis S. Makridis, George Litsardakis, Kostas G. Efthimiadis +6
High coercivity, the highest for Cu-free 2 : 17 Sm-Co ribbons, has been obtained in as-spun (= 211 kOe) and short time annealed (= 232 kOe) samples of Sm(CobalFe Zr B)7 5 alloys, w…
Effective ferromagnetic coupling between a superconductor and a ferromagnet in LaCaMnO/Nb hybrids
D. Stamopoulos, N. Moutis, M. Pissas +1
In this work we present magnetization data on hybrids consisting of multilayers (MLs) of man- ganites [La0.33Ca0.67MnO3/La0.60Ca0.40MnO3]15 in contact with a low-Tc Nb superconduct…
Relaxation measurements in the regime of the second magnetization peak in Nb films
D. Stamopoulos, D. Niarchos
We report on magnetic measurements as a function of field, temperature and time (relaxation) in superconducting Nb films of critical temperature Tc = 9.25 K. The magnetic measureme…
From the second magnetization peak to peak effect. A study of superconducting properties in Nb films and MgB2 bulk samples
Dimosthenis Stamopoulos, Athanasios Speliotis, Dimitris Niarchos
We report on magnetic and magnetoresistance measurements in two categories of superconducting Nb films grown via magnetron sputtering and MgB2 bulk samples. In the first category,…
