Abstract:

We study the conductivity and magnetic susceptibility of single-crystal iron monosilicide in ultrahigh magnetic fields (up to 500 T) at low temperatures. The experimental methods used in measuring the conductivity and magnetic susceptibility are discussed. At 77 K we detect a gradual increase in the conductivity of iron monosilicide by more than a factor of 100 as the magnetic field gets stronger. At 4.2 K we detect a first-order phase transition in a field of 355 T accompanied by a sudden change in the value of the magnetic moment by 0.95 mu(B) per iron atom and a transition to a phase with high conductivity. The results are discussed within the scope of the spin-fluctuation theory. (C) 1999 American Institute of Physics. {[}S1063-7761(99)02011-9].
