Olga Young, Laurent C. Chapon, Oleg A. Petrenko
TL;DR
This study investigates the low-temperature magnetic structure of SrHo2O4, revealing coexisting long-range and short-range magnetic orders due to geometric frustration, with persistent diffuse scattering above the ordering temperature.
Contribution
It provides the first detailed neutron diffraction analysis of SrHo2O4's magnetic structure, identifying coexisting magnetic components and their temperature dependence.
Findings
Long-range magnetic order appears at 0.68 K.
Coexistence of long-range and short-range magnetic structures.
Diffuse magnetic scattering persists well above T_N.
Abstract
SrHo2O4 is a geometrically frustrated compound because the Ho^3+ ions are arranged in a network of triangles and hexagons and coupled with antiferromagnetic exchange interactions. Powder neutron diffraction measurements show that long-range magnetic order is established at T_N = 0.68 K. The low temperature magnetic structure is made up of two distinct components: a k = 0 long-range structure as well as a shorter-range low-dimensional structure with scattering intensity around the (0 0 1/2) position. The diffuse component of the magnetic scattering from SrHo2O4 remains very intense at temperatures well above T_N.
