Title:
Field-Induced Magnetic Transition in the Heavy-Fermion Antiferromagnet ${\mathrm{Ce}}_{7}{\mathrm{Ni}}_{3}$ 
Abstract:
We present a detailed study of the field (B) - temperature (T) phase diagram of the heavy-fermion antiferromagnet Ce7Ni3 that crystallizes in the hexagonal Th7Fe3-type structure with three nonequivalent Ce sites (CeI, CeII, and CeIII). This compound undergoes two magnetic transitions at TN1=1.9K and TN2=0.7K in zero field. Below TN1, an incommensurate spin density wave (SDW) develops, and below TN2 a commensurate SDW appears independently. By applying fields along the c axis, both TN1 and TN2, a...    »
