Аннотация:Magnetic measurements and neutron powder diffraction investigation of the magnetic structure of the orthorhombic YNi4Si-type (space group Cmmm) NdNi4Si compound are presented.The magnetocaloric effect of NdNi4Si is calculated in terms of the isothermal magnetic entropy change and it reaches the maximum value of –3.3 J/kgK for a field change of 50kOe near TC¼12K. Below 12K, NdNi4Si exhibits a commensurate b-axis collinear ferromagnetic ordering with the Cmm0m magnetic space group in a zero magnetic field. At1.5K,the neodymium atoms have the magnetic moment of 2.37(5) μB. The orthorhombic crystal structure and its thermal evolution are discussed in comparison with the CaCu5-type compound.
