Magnetic structure of geometrically frustrated SrGd2O4
We propose to investigate the low temperature magnetic structure of the geometrically frustrated SrGd2O4 compound by powder neutron diffraction using a sample with non-absorbing Gd isotope. SrGd2O4 belongs to the SrLn2O4 (Ln = Lanthanide) crystal family. In this compound, magnetic ions are linked through a network of triangles and hexagons suitable for the establishment of magnetic frustration. Heat capacity measurements have revealed the presence of two magnetic transitions at TN1 = 2.72K and TN2 =0.47K. In field susceptibility measurement have also show the field sensibility as well as the anisotropy of the magnetic structure of this compound. Due to the spin only magnetic moment of Gd, SrGd2O4 gives a unique opportunity to study magnetism in the SrLn2O4 family member, whose properties are determined mostly by the exchange interactions, rather then by the single ion physics.
