Magnetic state in URu₂Si₂, UPd₂Al₃, and UNi₂Al₃ probed by point contacts
The antiferromagnetic (AFM) state has been investigated in the three heavy-fermion compounds URu₂Si₂,UPd₂Al₃, and UNi₂Al₃ by measuring dV/dI(V) curves of point contacts at different temperatures 1.5-20 K and magnetic fields 0-28 T. The zero-bias maximum in dV/dI(V) for URu₂Si₂ points to a partially...
