Evolution of Physical Properties of RE3Ni5Al19 Family (RE = Y, Nd, Sm, Gd, Tb, Dy, Ho, and Er)

Single crystals of RE3Ni5Al19 series (RE = Y, Nd, Sm, Gd, Tb, Dy, Ho, and Er) are grown using the Al self-flux method. The crystal structure is examined by both single crystal and powder X-ray diffraction. Physical properties are studied for the first time for RE3Ni5Al19 (RE = Y, Nd, Gd, Tb, Dy, Ho, and Er) by means of magnetic susceptibility, electrical resistivity, and heat capacity measurements. Complex magnetic behaviors, with up to three transitions present for RE = Sm, Gd, Tb, and Dy, are revealed. Y3Ni5Al19 is found to be a nonmagnetic nonsuperconducting metal (above T = 1.8 K) with weak electron-phonon coupling strength.
