Abstract:

Electrical resistivity, specific heat and magnetic phase transitions have been studied in Mn1.8Co0.2Sb and FeRh based compounds, where Fe and Ph are substituted by other d elements (Ni, Pd, Pt, Ir, Ru). In the antiferromagnetic state below a critical temperature, T-t, an external field induces first-order phase transitions accompanied by a giant magnetoresistance effect (of about - 60\% at room temperature) and by a significant enhancement of the electronic specific heat coefficient (up to 180\%), which are both strongly affected by the d electron concentration.
