Master Thesis: Magnetisierungsmessungen an festem 3He bei ultratiefen Temperaturen (2004)
Ph.D. Thesis: Kernspindynamik in festem 3He bei ultratiefen Temperaturen (2009)
In his Ph.D. thesis, Matthias Kath studied the magnetic properties of solid 3He under the supervision of apl. Prof. Erwin Schuberth down to 500 µK. Due to a direct particle exchange of the atoms, solid 3He offers a special opportunity to study the resulting magnetic ordering of the nuclear spins at mK-temperature. Nevertheless, the available data does not provide unambiguous information about the magnetic structure. Using spin echo methods and magnetization measurements based on NMR and SQUID magnetometry, he could verify the existence of 3He single crystallites in the silver sinter after the solid is tempered just below 1 mK.
