Abstract
It is well established that many material properties, such as multiferroicity, magnetoresistance, or magnetoelectricity, emerge from strong interactions of spins and lattice (phonons). An in-depth understanding of spin–phonon coupling is key to understanding these properties. We demonstrate strong spin–phonon coupling in HoCrO3 using powder X-ray diffraction measurements. Our investigations confirm magnetoelastic effects below antiferromagnetic phase transition, TN ≈ 142 K. The lattice parameters and unit cell volume decrease normally with temperature up to ∼ TN, but decrease anomalously below TN. By fitting the background thermal expansion for a non-magnetic lattice using the Debye–Grüneisen equation, we determined the lattice strain ∆VM due to the magnetoelastic effects as a function of temperature. We have also established that the lattice strain due to the magnetoelastic effect in HoCrO3 couples with the square of the ordered magnetic moment of the Cr3+ ion.
