“…Spin-polarized electron energy loss spectroscopy (SPEELS) developed in the 1980s and has become a valuable technique for probing Stoner excitations [1][2][3][4][5][6][7][8] and more recently spin waves [9]. In so-called spin flip exchange scattering, an incident electron of a given spin occupies an empty state of the target material and an electron of opposite spin is excited and detected.…”

“…Consequently SPEELS is a complementary technique to spin-resolved photoemission and inverse photoemission that more directly probe the occupied and unoccupied spin-split band structure respectively. SPEELS studies have been done using unpolarized electron sources with scattered electron spin detection [1], with spin-polarized sources without scattered electron spin detection [2,3], and with both spin-polarized sources and scattered electron spin detection [4][5][6][7][8].…”

“…As low energy electrons can penetrate only the first few atomic layers, SPEELS can be employed to investigate the elementary excitations of magnetic systems with reduced symmetry [3]. For example, the Stoner spectrum (electron hole pair spectrum) has been successfully explored by SPEELS [4,5]. The Stoner excitation involves, at least, a two state transition: A majority band electron interacts with an incoming polarized electron (of opposite spin projection) and goes over into a vacuum state.…”

“…In spin-polarized electron energy loss spectroscopy (SPEELS), such a virtual spin-flip process was found to be of similar strength as the direct scattering event without a spin-flip [59][60][61][62]. The magnon emission corresponds to multiple scattering between the primary electron and the hole of an electron-hole pair in the opposite spin channel (Feynman diagrams after Refs [20] and [21]).…”
