Spin kinetics of liquid 3He in an aerogel–DyF3 nanoparticle system

The pulsed NMR method was used to study the spin kinetics of liquid 3Не in a sample of oriented Al2O3 aerogel, containing DyF3 nanoparticles with an average size of 5 nm, at temperatures of 1.5−3 K. DyF3 is a dipole dielectric ferromagnet with a phase transition temperature of TC = 2.55 K, while the...

Zusammenfassung:The pulsed NMR method was used to study the spin kinetics of liquid 3Не in a sample of oriented Al2O3 aerogel, containing DyF3 nanoparticles with an average size of 5 nm, at temperatures of 1.5−3 K. DyF3 is a dipole dielectric ferromagnet with a phase transition temperature of TC = 2.55 K, while the diamagnetic ordered Al2O3 aerogel is used as a magnetic diluting agent to ensure the optimal conditions for observing the 3Не nuclear magnetic resonance in this system. No anomalies in the spin kinetics of 3Не contacting with this sample that could be related to the phase transition have been observed. A method for adding paramagnetic impurities to aerogel was proposed.
