Abstract
The crystal structure, magnetic transitional behaviors and magnetocaloric effect were investigated in Nd6Fe13Pd compound. The results show that Nd6Fe13Pd crystallizes in the tetragonal Nd6Fe13Si-type structure (space group I4/mcm) with the lattice parameters aâ¯=â¯bâ¯=â¯8.0765â¯Ã
and câ¯=â¯22.3747â¯Ã
and two magnetic transitions from the ferromagnetic to the antiferromagnetic states with Ttrâ¯=â¯173â¯K and from the antiferromagnetic to the paramagnetic states with the Néel temperature of 369â¯K occurred in the Nd6Fe13Pd compound. The magnetic transition between the ferromagnetic and the antiferromagnetic states can be induced by either changing temperature or applying a magnetic field with very small thermal and magnetic hystereses and the transition temperature is very sensitive to the applied field. The experimental results indicate a broad working temperature span and negative magnetic entropy changes around Ttrâ¯=â¯173â¯K. For a magnetic field change of 2â¯T, the maximum magnetic entropy change âÎSM reaches to 4.4â¯Jâ¯kgâ1â¯Kâ1 with the corresponding refrigeration capability of about 125â¯Jâ¯kgâ1.
