Broadband ferromagnetic resonance in Ni-Mn-Ga single crystal
Luděk 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 tra…
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…
A frustrated antipolar phase analogous to classical spin liquids
G. Bastien, D. Repček, A. Eliáš +17
The study of magnetic frustration in classical spin systems was motivated by the prediction and discovery of classical spin liquid states. These uncommon magnetic phases are charac…
Two Displacive Ferroelectric Phase Transitions in Multiferroic Quadruple Perovskite
A. Maia, M. Kempa, V. Bovtun +6
We report on the microwave, terahertz (THz), infrared and Raman spectroscopic studies of ceramics, shedding more light into the nature of two structural phase tran…
Microwave magnetic excitations in U-type hexaferrite SrCoZnFeO ceramics
M. Kempa, V. Bovtun, D. Repček +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…
Can the Ferroelectric Soft Mode Trigger an Antiferromagnetic Phase Transition?
André Maia, Christelle Kadlec, Maxim Savinov +10
Type-II multiferroics, where spin interactions induce a ferroelectric polarization, are interesting for new device functionalities due to large magnetoelectric coupling. We report…
