Magnetic chains are playgrounds for unconventional physics but emergence of 1D order in cannonical systems is associated with full 3D magnetic order. Uniquely, below 1.6 K, Tb(HCO2)3 is host to an ordered 1D Ising magnetic state, which is possible due to frustrated antiferromagnetic coupling between chains. As the weaker antiferromagnetic coupling becomes more significant below 1.0 K this frustration appears to be partially relieved by spin canting, leading to the emergence of a stripped phase. The structures of magnetic phases of Tb(HCO2)3 are becoming clearer but understanding of the energy scale of its low energy excitations is very limited. We will use the low energy LET spectrometer to probe each of the magnetic states of Tb(HCO2)3 to understand the energy scale of the interactions in this material to understand its dynamics and support theoretical studies of this unique compound.
