SHPM imaging of LiHoF 4 at ultra low temperatures

In the first part of this thesis we describe the functioning principle of the scanning hall probe microscope (SHPM), and we present a summary of the theoretical and experimental knowledge on the dipolar-coupled Ising ferromagnet LiHoF4. In the second chapter we present the experimental setup that allows us to perform SHPM imaging at ultra low temperatures. The main components; microscope head, ...

The Ballistic Behavior of High Strength, Low Alloy-100 Steel at Sub-zero Temperatures

The ballistic response of the high strength, low alloy (HSLA-100) steel at ambient and temperatures of -400°C, -800°C and -1960°C is investigated in this work. Lambert-jonas equation is used to fit the experimental results into a curve. The effect of quenching on ballistic behavior of HSLA-100 is also studied. The experiments are conducted on 3mm thick rectangular specimens impacted by blunt ti...

Ultra-high-Q phononic resonators on-chip at cryogenic temperatures

Long-lived, high frequency phonons are valuable for applications ranging from optomechanics to emerging quantum systems. For scientific as well as technological impact, we seek high-performance oscillators that offer a path towards chip-scale integration. Confocal bulk acoustic wave resonators have demonstrated an immense potential to support long-lived phonon modes in crystalline media at cryo...
