Magnetic structure of the ternary GdMn2Si2 compound and short-range magnetic order in Tb3Ni.
RMn2Si2 (R is a rare-earth metal) compounds crystallize in a natural layered crystal structure and exhibit a rich variety of magnetic structures and magnetic phase transitions. This proposal is focused on the neutron powder diffraction study of magnetic structure of the GdMn2Si2 compound that contains highly absorbing Gd atoms. It is expected that one-off measurement at low temperature will be performed on the D4 instrument in order to solve the magnetic structure of GdMn2Si2. We also plan to perform testing measurements on the Tb3Ni powder sample exhibiting a short-range magnetic order in a wide temperature range up to 5-6 times the Neel temperature. It is expected that the results of this experiment help us to prepare a normal access proposal for study of the short-range magnetic order effect in binary rare-earth intermetallic Tb3T (T=Co, Ni) and R5Pd2 compounds.
