“…Mg 2 Sn exhibits the same value, and Sn was assigned the valence state 0 [41]. CeRhSn also shows a comparable value of δ = 1.81 mm s −1 at 293 K [24,42], and the quadrupolar splittings and line widths show nearly the same values in all measurements. As expected, the non-cubic site symmetry results in small quadrupolar splittings of about ∆E Q ≈ 0.55 mm s −1 .…”

The solid solutions Ce(Rh 1−x Ru x )Sn were investigated by means of susceptibility measurements, specific heat, electrical resistivity, X-ray absorption spectroscopy (XAS), and 119 Sn Mössbauer spectroscopy. Magnetic measurements as well as XAS data show a cerium valence change in dependence on the ruthenium content. Higher ruthenium content causes an increase from 3.22 to 3.45 at 300 K. Furthermore χ and χ −1 data indicate valence fluctuation for cerium as a function of temperature. For example, Ce(Rh 0.8 Ru 0.2 )Sn exhibits valence fluctuations between 3.42 and 3.32 in the temperature range of 10 to 300 K. This could be proven by using the interconfiguration fluctuation (ICF) model introduced by Sales and Wohlleben. Cerium valence change does not influence the tin atoms as proven by 119 Sn Mössbauer spectroscopy, but it influences the electrical properties. Ce(Rh 0.9 Ru 0.1 )Sn behaves like a typical valence fluctuating compound, and higher ruthenium content causes an increase of the metallic behavior.

“…Mössbauer studies [312,314,570,571,572,573] on RRhSn compounds show that there is no magnetic hyperfine field splitting in 119 Sn spectra for LaRhSn and CeRhSn which indicates absence of long range magnetic order. The analysis of 119 Sn Mössbauer spectra reveals that the directions of moments in Pr and Nd compounds are close to c-axis [312,573].…”

RTX (R=rare earths, T= 3d/4d/5d, transition metals such as Sc, Ti, Mn, Fe, Co, Ni, Cu, Ru, Rh, Pd, Ag, Os, Ir, Pt, Au, and X=p-block elements such as Al, Ga, In, Si, Ge, Sn, As, Sb, Bi) series is a huge family of intermetallics compounds. These compounds crystallize in different crystal structures depending on the constituents. Though these compounds have been known for a long time, they came to limelight recently in view of the large magnetocaloric effect (MCE) and magnetoresistance (MR) shown by many of them. Most of these compounds crystallize in hexagonal and tetragonal crystal structures. Some of them show crystal structure modification with annealing temperature; while a few of them show iso-structural transition in the paramagnetic regime. Their magnetic ordering temperatures vary from very low temperatures to temperatures well above room temperature (~510 K). Depending on the crystal structure, they show a variety of magnetic and electrical properties.These compounds have been characterized by means of a variety of techniques/measurements such as x-ray diffraction, neutron diffraction, magnetic properties, heat capacity, magnetocaloric properties, electrical resistivity, magnetoresistance, thermoelectric power, thermal expansion, Hall effect, optical properties, XPS, Mössbauer spectroscopy, ESR, μSR, NMR, NQR etc. Some amount of work on theoretical calculations on electronic structure, crystal field interaction and exchange interactions has also been reported. The interesting aspect of this series is that they show a variety of physical properties such as Kondo effect, heavy fermion behavior, spin glass state, intermediate valence, superconductivity, multiple magnetic transitions, metamagnetism, large MCE, large positive as well as negative MR, spin orbital compensation, magnetic polaronic behavior, pseudo gap effect etc.Except Mn, no other transition metal in these compounds possesses considerable magnetic moments.Because of this RMnX compounds in general have high ordering temperatures. Interstitial modification using hydrogen and nitrogen is found to alter their crystal structures and magnetic properties considerably. RTX compounds also show interesting pressure effects on their structural and magnetic properties. In summary, these compounds show variety of physical properties over a wide range of temperatures. This review is intended to cover all the important results obtained in this family, particularly in the last few years.

“…These compounds belong to the rich family of R(A)-T-X (R − rare earth or A − actinide element, T − d metal, X − p element) ternary intermetallics [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21], which present a variety of crystal and magnetic structures and a plethora of interesting physical properties, including complex magnetism, unconventional superconductivity, and intermediate valence. Magnetic susceptibility and heat capacity results show that LuZnSn 2 compound does not undergo any magnetic phase transition down to 1.9 K [1,22], and therefore this compound is an ideal reference material for the estimation of magnetic contributions to heat capacity of magnetically ordered isostructural compounds.…”

Abstract. New analysis of heat capacity data is presented for LuZnSn 2 compound that takes into account anharmonic effects together with the existence of Einstein modes. Sn Mössbauer spectroscopy was used to monitor the hyperfi ne parameters at the two crystallographically inequivalent Sn sites in the studied compound. The problem of non-unique mathematical resonance spectrum description and the problem how to choose physically meaningful set of hyperfi ne parameters will be thoroughly discussed. Measured quadrupole interaction constants by 119m Sn Mössbauer spectroscopy give estimations for V zz component of electric fi eld gradient tensor at both Sn sites in LuZnSn 2 .
