Theory of antiferromagnetic resonance
WebbThe antiferromagnetic resonance spectrum of single-crystal Cr 2 O 3 has been mapped within the wavelength region from 12 mm to 2.8 mm and magnetic field intensities from 0 oersteds to 30 000 oersteds. The resonance frequencies were observed in this region in a temperature interval from about 17°C to 35°C, the Néel temperature, T N. Webb29 maj 2024 · Antiferromagnetic resonance (AFMR) experiments on a well characterized single-crystal sample of MnF2 have been performed using a spectrometer with wide ranges of both frequency and magnetic field. All the AFMR modes predicted from the …
