摘要：
Magnetic, heat capacity and magnetocaloric properties of non-stoichiometric TbMn0.33Ge2 compound have been studied. Different measurements show that it undergoes three magnetic transitions at T-N T-1 and T-2. The magnetocaloric effect has been estimated from magnetization data using Maxwell's relation. The existence of collinear and sine wave modulated components makes the magnetic structure complex at low temperatures. It is also found that this compound shows normal and inverse magnetocaloric effects in different temperature regimes. (C) 2014 Elsevier B.V. All rights reserved.
