Phys. Rev. B 65, 132409 (2002) [4 pages]Magnetic properties of Fe1-xCoxSi alloys
M. K. Chattopadhyay, S. B. Roy, and Sujeet Chaudhary Received 14 December 2001; published 19 March 2002 The solid solution between nonmagnetic narrow-gap semiconductor FeSi and diamagnetic semimetal CoSi gives rise to interesting metallic alloys with long-range helical magnetic ordering, for a wide range of intermediate concentrations. We report various magnetic properties of these alloys, including low-temperature reentrant spin-glass like behavior and an inverted magnetic hysteresis loop. The role of Dzyaloshinski-Moriya interaction in the magnetic response of these non-centro-symmetric alloys is discussed. ©2002 The American Physical Society
