Abstract
High-field AFMR measurement of Nd2BaNiO5 powder has been performed for the first time in the frequency region from 50 to 383 GHz using the p ulsed magnetic field up to 16 T at 1.8 K. Two magnetic transitions at B-c1 = 9.6 T and B-c2 = 16.2 T were also observed by our magnetization measurement at 4.2 K. Two distinct AFMR modes with gaps of about 240 GHz and 1 THz, and the change of AFMR modes at B-c1 were observed. The attribution of these modes are discussed. (C) 1998 Elsevier Science B .V.
