“…More than a hundred ternary intermetallic compounds are known to form in the Heusler structure type, and due to the richness of their physical properties, they are one of the most interesting intermetallic families known. In this class of materials a wide variety of magnetic and electrical transport properties 2,3 including magnetic ordering 4,5 heavy fermion behavior 6,7,8,9,10 , shape memory effect 11 , half-metallic ferromagnetism 12 and semimetallic 4,5 behavior have been found. Moreover, several Heusler phases have been discovered to have a superconducting ground state (see Refs.…”

Several physical properties of the superconducting Heusler compounds, focusing on two systems (Y, Lu, Sc)Pd 2 Sn and APd 2 M, where A=Hf, Zr and M=Al, In, are summarized and compared. The analysis of the data shows the importance of the electron-phonon coupling for superconductivity in this family. We report the superconducting parameters of YPd 2 Sn, which has the highest T c among all known Heusler superconductors.

“…Intensities and peak widths of several Bragg re¯ec-tions were measured so as to check the crystallinity and to determine the LRO parameter of our sample using the method of Takayanagi et al (1988). The 006 and 339 Bragg re¯ections were corrected for Lorentz±polariza-tion effects.…”

“…In fact, slight structural disorder has already been reported for CeInCu 2 . According to Takayanagi et al (1988), $10% of Ce atoms are exchanged by In atoms and vice versa [the long-range order (LRO) parameter S (probability of ®nding a Ce atom at a Ce site) À (probability of ®nding an In atom at a Ce site) 9 0.8].…”

By using the X-ray diffraction technique, residual shortrange order was detected in CeInCu 2 , cerium dicopper indium, which is known to be a heavy fermion compound. In spite of the long-range order of this substance, diffuse scattering exhibiting short-range order was observed at room temperature. The correlation parameters obtained showed that an incorrectly occupied lattice site has a tendency to gather atoms of different species at the neighboring sites along the h111i directions. Thus, the disordered region would form a cluster composed of several disordered atoms. Furthermore, a chain-type correlation which has a period of 20± 23 A Ê along the same directions was indicated. The superstructure-like feature of the disordered atoms hardly increases the residual resistivity. It is consistent with the behavior of the residual resistivity under high pressure.

“…The properties of many of them are interesting for various fields of science and technology and have intensively been investigated. Specifically, the CeCu 2 In [4][5][6] and CeCu 4.38 In 1.62 [7,8] compounds are heavy-fermion systems and the compounds CeMIn 5 and Ce 2 MIn 8 (M = Co, Rh, Ir) combine antiferromagnetism with superconductivity [9][10][11]. The compounds with the AlB 2 -type structure in the RE-M-In system (M = Cu, Ni) constitute a big group of ternary rare-earth indides with transition metals.…”
