Aggregate Frequency Width, Nuclear Hyperfine Coupling and Jahn-Teller Effect of Impurity Ion ESR in Dielectric Resonator at Millikelvin
M. A. Hosain, J. -M. Le Floch, J. Krupka +1
The impurity paramagnetic ion, substitutes in the single crystal lattice, this results in a elongated octahedron, the resulting measured g-factor…
Rigorous ESR spectroscopy of impurity ion with oxygen vacancy in ferroelectric crystal at 20 mK
M. A. Hosain, J-M. Le Floch, J. Krupka +1
Impurity ion electron spin resonance (ESR) spectroscopy using multiple dielectric modes in a dielectric resonator has been performed with a tuneable DC magnetic…
Precision Multi-Mode Dielectric Characterization of a Crystalline Perovskite Enables Determination of the Temperature-Dependent Phase Transitions
Zijun C. Zhao, Maxim Goryachev, Jerzy Krupka +1
Simple perovskite crystals undergo structural phase transitions on cooling to low temperatures, which significantly change the material properties of the crystal. In this work we r…
Electrodynamic improvements to the theory of magnetostatic modes in ferrimagnetic spheres and their applications to saturation magnetization measurements
Jerzy Krupka, Adam Pacewicz, Bartlomiej Salski +4
Electrodynamic theory applied to the analysis of TEn0p mode resonances in ferromagnetic spheres placed either in metallic cavities or in the free space is compared with Walker-Flet…
Frequency-Temperature sensitivity reduction with optimized microwave Bragg resonators
Jean-Michel Le Floch, Christopher Murphy, John Gideon Hartnett +4
Dielectric resonators are employed to build state-of-the-art low-noise and high- stability oscillators operating at room and cryogenic temperatures. A resonator temperature coeffic…
Determination of the Anisotropy of Permittivity of Quantum Paraelectric Strontium Titanate
Maxim Goryachev, Lingfei Zhao, Zijun Zhao +3
The dielectric properties of strontium titanate (SrTiO) have previously been reported from room temperature to low temperatures with conflicting results. In this work, precisio…
