Antiferromagnetic resonance in a GdCr3(BO3)4 crystal

Antiferromagnetic resonance in a GdCr3(BO3)4 crystal

An experimental study of AFMR in a GdCr3(BO3)4 single crystal within the frequency range of 17–38 GHz, at the temperature 4.2 K, was performed. The determined value of the energy gap in spin-wave spectrum equals (25.5 ± 0.5). It was shown that the high-frequency properties of gadolinium chromium bor...

Zusammenfassung:An experimental study of AFMR in a GdCr3(BO3)4 single crystal within the frequency range of 17–38 GHz, at the temperature 4.2 K, was performed. The determined value of the energy gap in spin-wave spectrum equals (25.5 ± 0.5). It was shown that the high-frequency properties of gadolinium chromium borate are well defined within the framework of a two-sublattice antiferromagnet model with “easy-plane” anisotropy.
