Spin magnetic moment of Tm atoms equals 2.16 μB confirming its Tm3+ state. Calculated elastic properties as well as Vickers hardness of TmNiSb alloy was defined semi-empirically and equals 15.98 GPa. Experimentally determined microhardness is within the range of 2.90 – 4.06 GPa with the exception of TmNiSb phase.262-264enthermoelectric materialDFT+U modelinghalf- Heusler phasesspin magnetic momentmechanical propertiesConference Abstract© Національний університет “Львівська політехніка”, 20173Experimental and First-principle study of TmNiSb half-Heusler Alloy / Zlata Rykavets, Diana Ryzhak, Lyubov Romaka, Sergiy Shvachko, Vitaliy Romaka // Litteris et Artibus : proceedings, 23–25 November, 2017. — Lviv : Lviv Polytechnic Publishing House, 2017. — P. 262–264. — (6th International academic conference «Mechanical engineering, materials science, transport 2017» (MEMST-2017)).
