Abstract

Low-temperature specific heat and its field-dependence up to 16T was measured in a stoichiometric single crystal of YbP. A sharp peak was observed at T_N = 0.53 K in zero magnetic field. Application of external field seems to induce a new magnetic phase above 11T. The field dependence of the transition temperature in the high-field phase is different from that of the low field phase. The linear coefficient of the electronic specific heat is estimated as 120 mJ/mol·K² from low temperature specfic heat, suggesting heavy Fermion state in YbP.
