“…Mössbauer studies suggest non-collinear magnetic structures in NdRhSn [573], GdRhSn [318], DyRhSn [321,323,574], HoRhSn [323,324] and SmRhSn [315,575] [269]. It has been observed that the value of hypefine field is different and shows a large variation for these compounds below their ordering temperatures.…”

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.

“…Представителями данной серии являются интерметаллиды GdRhSn и TbRhSn. Их структурные, электронные, магнитные и тепловые свой-ства изучались в работах [2][3][4][5][6][7]. Исследования темпера-турных зависимостей электросопротивления, магнитной восприимчивости, намагниченности и теплоемкости [5,7] свидетельствуют о существовании в этих сплавах ан-тиферромагнитного (АФМ) упорядочения с температу-рами Нееля T N , равными 16.2 K (GdRhSn) и 18.3 K (TbRhSn).…”

Проведены исследования электронной структуры и оптических свойств соединений GdRhSn и TbRhSn. Расчеты зонного спектра с учетом спиновой поляризации выполнены в приближении локальной электронной плотности с поправкой на сильные корреляционные эффекты в 4 f -оболочке редкоземельного металла (метод LSDA + U). Оптические свойства исследованы эллипсометрическим методом в широком диапазоне длин волн, определен ряд спектральных и электронных характеристик. Показано, что оптическое поглощение в данных соединениях в области межзонных переходов находит удовлетворительное объяснение в рамках проведенных расчетов плотностей электронных состояний.Работа выполнена в рамках государственного задания ФАНО России (тема " Электрон", № 01201463326) при частичной поддержке РФФИ (проекты № 16-52-48012 и 17-52-45056). А.В.Л. благодарит за поддержку Правительство РФ (постановление № 211, контракт № 02.A03.21.0006).

“…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 .
