High-Frequency and Microwave Magnetic Properties of NiZnFeO Spinel Ferrite Ceramics
M. Kempa, V. Bovtun, V. Kukhar +5
Magnetic properties of the NiZnFeO (NZF) spinel ferrite ceramics were studied over a broad frequency range (1 MHz - 50 GHz). Between 10 MHz and 2 GHz, stron…
Broadband ferromagnetic resonance in Ni-Mn-Ga single crystal
LudÄk Kraus, Denys Musiienko, Martin Kempa +1
We present a broadband ferromagnetic resonance study in single crystalline NiMnGa in the temperature range from room temperature to 120 °C in which the tr…
Weak-field FMR and magnetization near the collinear to conical ferrimagnetic phase transition in the U-type hexaferrite Sr4CoZnFe36O60 ceramics
Martin Kempa, Viktor Bovtun, Dalibor RepÄek +2
Temperature evolution of the ferromagnetic resonance (FMR) and its interference with other microwave (MW) magnons near the collinear to conical ferrimagnetic phase transition at Tc…
Microwave magnetic excitations in U-type hexaferrite SrCoZnFeO ceramics
M. Kempa, V. Bovtun, D. RepÄek +3
Microwave (MW) transmission, absorption, and reflection loss spectra of the ferrimagnetic U-type hexaferrite SrCoZnFeO ceramics were studied from 100 MHz to 35 GH…
