Thermal expansion and magnetostriction in RAl$_3$ (R = Tm,Yb,Lu) single crystals

ORAL

Abstract

We present temperature dependent thermal expansion and low temperature longitudinal magnetostriction measurements taken using a capacitance dilatometer [G.M. Schmiedeshoff et al., RSI, in press] in a PPMS-14 instrument for several cubic RAl$_3$ (R = rare earth) compounds. Quantum oscillations in the magnetostriction were observed in LuAl$_3$ and YbAl$_3$, including few new frequences for the latter. Data on qualitative changes in TmAl$_3$ thermal expansion in presence of the longitudinal magnetic field will be presented and discussed.
