High temperature anisotropy of NdFeO3 determined using time-domain THz spectroscopy

Conference Paper


Abstract

  • The temperature dependent anisotropic fields along two principal crystallographic axes (Ax and Az) is calculated for the canted antiferromagnet neodymium iron oxide in the temperature range 300 - 470 K. The calculation is performed using the experimentally determined temperature dispersion of two orthogonal antiferromagnetic magnons, obtained via time-domain terahertz spectroscopy. The experiment demonstrates the potential use of THz spectroscopy for characterising magnetic materials and offers a complementary technique to traditional neutron and magnetic methods.
