The magnetic field induced ferromagnetism in EuPd${}_2$Sn${}_4$ novel compound

Abstract

We report on crystal structure, magnetic and thermal physical properties of EuPd${}_2$Sn${}_4$ stannide. From the magnetic susceptibility measurements a divalent state of Eu rare earth element was determined together with an antiferromagnetic (AFM) order at 11 K. By applying magnetic field, the magnetic behavior variation reveals a complex magnetic structure. Above a critical field Bc a ferromagnetic (FM)-like character starts to prevail. AFM and FM regimes are separated by a metamagnetic region. Heat capacity measurements confirm this behavior.
