Title: High field magnetization and specific heat of ErNi{sub 5}

Abstract

High field magnetization studies of single crystalline ErNi{sub 5} in fields up to 38T at 1.5K along the main crystallographic directions have been performed. Along the easy direction, the hexagonal axis, the spontaneous magnetization, M{sub s}, amounts to 8.62{mu}{sub B}/f.u. The high-field susceptibility is very small and equal to 41 {times} 10{sup {minus}4}{mu}{sub B}/Tf.u. There exists a distinct difference between the curves along the a- and b-axis. The a-axis curve monotonously increases with field up to 38T. The b-axis curve coincides with the a-axis curve up to 12T but starts to deviate from it above this field, resulting in a value for the magnetization at 38T which is almost the full moment value. The specific beat of a newly-grown single-crystalline sample has been measured in zero field and in applied fields along the c-axis (B = 0.3, 1, 2, 5T). The zero-field measurements coincide with previously reported results The specific heat shows a rapid decrease of the ferrimagnetic order with applied field. Already in 1T, the sharp lambda-type of peak at the magnetic transition is decreased by two third and becomes a broad bump that coincides with the la measurement above 30K. Higher fields further suppress the transition.
