On the inverse and conventional magnetocaloric effects in MnRhAs single crystals
M. Balli, D. Fruchart, R. Zach
We report on the magnetic and magnetocaloric properties of a MnRhAs single crystal. The ternary arsenide exhibits a rather complex magnetic behaviour. A first order metamagnetic ty…
Ferromagnetic (Ga,Mn)N epilayers versus antiferromagnetic GaMnN clusters
R. Giraud, S. Kuroda, S. Marcet +7
Mn-doped wurtzite GaN epilayers have been grown by nitrogen plasma-assisted molecular beam epitaxy. Correlated SIMS, structural and magnetic measurements show that the incorporatio…
Enlarging the magnetocaloric operating window of the Dy2NiMnO6 double perovskite
M. Balli, S. Mansouri, P. Fournier +6
In this paper, we mainly focus on the magnetic and magnetocaloric features of La2-xDyxNiMnO6 double perovskites. Their magnetocaloric properties are investigated in terms of both e…
Competition of ferromagnetism and superconductivity in Sc3InB
B. Wiendlocha, J. Tobola, S. Kaprzyk +2
We present results of electronic structure calculations for intermetallic perovskite Sc3InB with Full--Potential KKR-LDA method. Sc3InB is very promising candidate for a new superc…
Two Gap State Density in MgB: A True Bulk Property or A Proximity Effect?
F. Giubileo, D. Roditchev, W. Sacks +7
We report on the temperature dependence of the quasiparticle density of states (DOS) in the simple binary compound MgB2 directly measured using scanning tunneling microscope (STM).…
High-Temperature Activated AB2 Nanopowders for Metal Hydride Hydrogen Compression
E. D. Koultoukis, E. I Gkanas, S. S. Makridis +3
A reliable process for compressing hydrogen and for removing all contaminants is that of the metal hydride thermal compression. The use of metal hydride technology in hydrogen comp…
Magnetotransport and the upper critical magnetic field in MgB2
P. Szabo, P. Samuely, A. G. M. Jansen +4
Magnetotransport measurements are presented on polycrystalline MgB2 samples. The resistive upper critical magnetic field reveals a temperature dependence with a positive curvature…
Magnetocaloric properties of Fe_{2-x}T_xP (T = Ru and Rh) from electronic structure calculations and magnetisation measurements
B. Wiendlocha, J. Tobola, S. Kaprzyk +3
An analysis of the magnetocaloric properties of the pure and substituted Fe2P compounds is made based on KKR-CPA electronic structure calculations and magnetisation M(H,T) measurem…
Evidence for two superconducting energy gaps in MgB2 by point-contact spectroscopy
P. Szabo, P. Samuely, J. Kacmarcik +6
Experimental support is found for the multiband model of the superconductivity in the recently discovered system MgB2 with the transition temperature Tc = 39 K. By means of Andreev…
