Journal ArticleDOI
Superconductivity on the Border of Weak Itinerant Ferromagnetism in UCoGe
N.T. Huy,A. Gasparini,D.E. de Nijs,Yingkai Huang,J.C.P. Klaasse,T. J. Gortenmulder,A. de Visser,A. Hamann,T. Görlach,Hilbert von Löhneysen +9 more
TL;DR: The proximity to a ferromagnetic instability, the defect sensitivity of T(s), and the absence of Pauli limiting, suggest triplet superconductivity mediated by criticalferromagnetic fluctuations.
Journal ArticleDOI
Structure, magnetism, and magnetocaloric properties of MnFeP1−xSix compounds
D. T. Cam Thanh,E.H. Brück,N.T. Trung,J.C.P. Klaasse,K.H.J. Buschow,Z.Q. Ou,Ojiyed Tegus,Luana Caron +7 more
TL;DR: In this paper, the structural, magnetic, and magnetocaloric properties are investigated as a function of temperature and magnetic field, and X-ray diffraction studies show that the samples in the range from x=0.28 to 0.64 adopt the hexagonal Fe2P-type structure with a small amount of second phase which increases with increasing Si content.
Journal ArticleDOI
Magnetocaloric effect in MnFe(P,Si,Ge) compounds
TL;DR: In this paper, the magnetocaloric effect in MnFe(P,Si,Ge) compounds was studied by x-ray diffraction and the homogeneity and the stoichiometry of the compounds were checked by electron probe microanalysis.
Journal ArticleDOI
CeCu2Ge2: Magnetic order in a Kondo lattice
F.R. de Boer,J.C.P. Klaasse,P.A. Veenhuizen,A. Böhm,C. D. Bredl,U. Gottwick,H. M. Mayer,L. Pawlak,U. Rauchschwalbe,H. Spille,Frank Steglich +10 more
TL;DR: Magnetic, calorimetric and transport measurements characterize CeCu2Ge2 as a Kondo-lattice system which orders antiferromagnetically below TN = (4.15 ± 0.05) K as mentioned in this paper.
Journal ArticleDOI
Magnetic phase transition and magnetocaloric effect in Mn5-xFexSi3
Songlin,Songlin,Dagula,Dagula,O. Tegus,O. Tegus,E.H. Brück,J.C.P. Klaasse,F.R. de Boer,K.H.J. Buschow +9 more
TL;DR: In this article, the magnetic phase transitions and magnetocaloric properties of the pseudo binary system Mn 5− x Fe x Si 3 with x = 0, 1, 2, 3, 4, 5 have been investigated by measuring the magnetisation as a function of temperature and magnetic field.
