Magnetic and structural instabilities in CePd2Al2 and LaPd2Al2
Magnetic and structural instabilities in CePd2Al2 and LaPd2Al2
We have investigated the crystal and magnetic structure of the RPd2Al2 compounds (R=La, Ce) by neutron powder diffraction (ND) and inelastic neutron scattering (INS). The ND study shows that both compounds undergo a structural phase transition from tetragonal to orthorhombic symmetry at 91.5 K (La) and 13.5 K (Ce). In the case of CePd2Al2 the crystal field excitation spectrum, which has an extra peak that cannot be explained by a standard crystal field model, indicates the presence of strong magneto-elastic coupling.

Abstract
We have investigated the crystal and magnetic structure of the RPd2Al2 compounds (R=La, Ce) by neutron powder diffraction (ND) and inelastic neutron scattering (INS). The ND study shows that both compounds undergo a structural phase transition from tetragonal to orthorhombic symmetry at 91.5 K (La) and 13.5 K (Ce). In the case of CePd2Al2 the crystal field excitation spectrum, which has an extra peak that cannot be explained by a standard crystal field model, indicates the presence of strong magneto-elastic coupling.
