Weak-field FMR and magnetization near the collinear to conical ferrimagnetic phase transition in the U-type hexaferrite Sr4CoZnFe36O60 ceramics
Original language description
Temperature evolution of the ferromagnetic resonance (FMR) and its interference with other microwave (MW) magnons near the collinear to conical ferrimagnetic phase transition at Tc2 = 305 K is found to correlate with the evolution of the weak-field magnetization: from two components in the conical phase to one component in the collinear phase. The FMR splitting above Tc2 correlates with the splitting of the coercive fields of the two magnetization components. A high sensitivity of the FMR to the weak magnetic bias near Tc2 is shown to be caused by the gradual transformation of the conical spin magnetic moments to the longitudinal ones. Application of the weak magnetic bias allows to adjust the MW absorption, and its level of above 30 dB is achieved near the FMR frequency (5.7-7.2 GHz), that allows to consider the Sr4CoZnFe36O60 hexaferrite ceramics as a possible MW absorbing material.
