Abstract

PrInNi₄ is a particularly interesting magnetic system which may be compared with PrNi₅, a Van-Vleck paramagnet displaying nuclear magnetic ordering below 0.4 mK. Our heat capacity measurements on PrInNi₄ reveal that it undergoes a ferromagnetic transition at T_C = 0.75 K and show that T_C rises dramatically with field, such that T_C = 9 K at 6 T. We have determined the magnetic excitations in PrInNi₄ using the HET spectrometer at ISIS. The lowest energy mode softens as q → 0, consistent with the low temperature ferromagnetic order.
