Antiferromagnetic resonance of polycrystalline BiMn$_{2}$O$_{5}$
Antiferromagnetic resonance of polycrystalline BiMn$_{2}$O$_{5}$
Multi-frequency electron spin resonance (ESR) measurements in polycrystalline samples of BiMn2O5 were employed to observe antiferromagnetic resonances (AFMR) in the range 0–14 T below the Néel temperature. The experimental data were analyzed using the phenomenological theory of Yosida and Nagamiya....

Multi-frequency electron spin resonance (ESR) measurements in polycrystalline samples of BiMn2O5 were employed to observe antiferromagnetic resonances (AFMR) in the range 0–14 T below the Néel temperature. The experimental data were analyzed using the phenomenological theory of Yosida and Nagamiya. Three resonance modes were identified in the xz (ac) plane from the data at 5 K. Macroscopic constants of anisotropy K1=12.5×106 erg/cm3 and K2=7.0×106 erg/cm3 were calculated allowing for the single-site anisotropy constant K′ to be estimated at T=0 K. The obtained value shows reasonable agreement with theoretical predictions. |
