Tuning the magnetocaloric effect in the Lu-doped frustrated Shastry-Sutherland system TmB4

Abstract: TmB 4 is an anisotropic, metallic magnetic system with geometrical frustration of the Shastry-Sutherland type. Here an experimental study of the magnetocaloric effect (MCE) in Lu doped Tm 1-x Lu x B 4 (x = 0.06, 0.30), evaluated from the temperature dependence of heat capacity and magnetization curves at 2 K, is presented. The results are described within a theoretical model based on an extended Ising Hamiltonian which considers interactions up to the 4th next nearest neighbours. Model parameters were optimize… Show more
