Breaking symmetry to create a parallel-plate varactor dielectric with unparalleled microwave performance
Florian Bergmann, Matthew R. Barone, Zishen Tian +24
Voltage-tunable capacitors (varactors) are key to microwave circuits. Tunable dielectric varactors outperform competing technologies in almost every relevant metric but usually suf…
Lattice dynamics and spin-phonon interaction in strained NiO films
Alireza Kashir, Veronica Goian, Daseob Yoon +4
NiO thin films with various strains were grown on SrTiO3 (STO) and MgO substrates using a pulsed laser deposition technique. The films were characterized using an x-ray diffractome…
Spin-phonon interaction increased by compressive strain in antiferromagnetic MnO thin films
Alireza Kashir, Veronica Goian, Oliva Pacherova +3
MnO thin films with various thicknesses and strains were grown on MgO substrates by pulsed laser deposition, then characterized using x-ray diffraction and infrared reflectance spe…
Unusual ferroelectric and magnetic phases in multiferroic 2H-BaMnO ceramics
Stanislav Kamba, Dmitry Nuzhnyy, Maxim Savinov +16
The structural phase transition in hexagonal BaMnO occurring at =130 K was studied in ceramic samples using electron and X-ray diffraction, second harmonic generation as w…
Electromagnon in the Z-type hexaferrite
Filip Kadlec, Christelle Kadlec, Jakub Vit +12
We studied experimentally the high-temperature magnetoelectric prepared as ceramics (x = 0, 0.2) and a single crystal (x = 0.5…
Spin and lattice excitations of a BiFeO3 thin film and ceramics
S. Skiadopoulou, V. Goian, C. Kadlec +7
We present a comprehensive study of polar and magnetic excitations in BiFeO3 ceramics and a thin film epitaxially grown on an orthorhombic (110) TbScO3 substrate. Infrared reflecti…
