ULTRASONIC AND MAGNETIZATION STUDIES AT THE METAMAGNETIC TRANSITION IN UPt3
TL;DR: In this paper, the velocity and attenuation of longitudinal ultrasound were measured on two single crystals of UPt3 in magnetic fields up to 33 T and temperatures down to 40 mK.
Journal ArticleDOI
Instrumentation for cryogenic microwave cavity resonance measurements
TL;DR: In this article, the authors describe instrumentation and measurement procedures for performing microwave measurements on small metallic samples at dilution refrigerator temperatures using the microwave cavity perturbation technique using the lead-plated cavity.
Journal ArticleDOI

TL;DR: In this paper, the authors performed ultrasonic velocity measurements on a single crystal of URu2Si2 at various temperatures in the 20 ms 50T pulsed magnets at the NHMFL, Los Alamos, NM.
Journal ArticleDOI
Velocity dispersion at the metamagnetic transition in UPt3
TL;DR: In this article, the longitudinal attenuation and velocity were measured on a single crystal of UPt 3 in magnetic fields up to 27 T. Simultaneous measurements at three frequencies during the same run were possible.
Journal ArticleDOI
Ultrasonic spectrometers for condensed matter studies at very high magnetic field
TL;DR: Three ultrasonic spectrometers have been constructed for use with the continuous and pulsed magnetic field facilities of the NHMFL at the Tallahassee and Los Alamos sites as mentioned in this paper.
