Structural and Magnetic Properties of EuIr<sub>3</sub>Si<sub>7 </sub>Single Crystals

ORAL

Abstract

Recently, Eu-based intermetallic compounds have been reported to exhibit complex magnetic textures. In this talk, I will present the physical properties of a new member, the EuIr3Si7 single crystal, of the RT3M7 family. This family of compounds has already shown interesting magnetic properties such as anomalous metamagnetism in YbRh3Si7, ferromagnetic ordering along the hard axis in YbIr3Ge7, and charge-neutral fermions in YbIr3Si7. EuIr3Si7 crystallizes in the ScRh3Si7 structure type with space group R-3c. Furthermore, it exhibits two magnetic phases below TN1 = 5 K and TN2 = 15 K, with easy-axis anisotropy. The presentation discusses two magnetic phases assessed using magnetization, specific heat, ac susceptibility, and neutron diffraction data.
