【 摘 要 】

The LiFeP sample has been prepared by means of high-temperature solid-state reaction. A transition temperature to the superconducting state was found as about 5.5 K by measurements of magnetization versus temperature. The second critical field was found above 1 kOe. Mossbauer spectra of the LiFeP phase are characterized by the quadrupole split doublet having splitting of about 0.10 mm/s at room temperature and 0.12 mm/s at 4.2 K. No magnetic order occurs down to 4.2 K. (C) 2010 Elsevier B.V. All rights reserved.
