Description:
Author(s): T. Chatterji, A. Stunault, and P. J. Brown The unique properties of zero-magnetization ferromagnets (ZMF) are well suited for device applications to process the spin of charged particles. The present paper is the first single-crystal polarized neutron diffraction study of the orbital and spin magnetic moments as a function of temperature through the compensation point of the ZMF Sm 1 − x Gd x Al 2 . This study is difficult because of enormous absorption of both Sm and Gd with thermal neutrons and was therefore not undertaken before. By using hot polarized neutrons and an applied magnetic field of 8 Tesla, the authors successfully determined spin and orbital moments of Sm 3 + ions separately with high accuracy. This study enables a better understanding of the basic microscopic mechanism of ZMF materials. [Phys. Rev. B 97, 064417] Published Tue Feb 20, 2018
