Magnetoelastic coupling and competing entropy changes in substituted CoMnSi metamagnets

We use neutron diffraction, magnetometry, and low-temperature heat capacity to probe giant magnetoelastic coupling in CoMnSi-based antiferromagnets and to establish the origin of the entropy change that occurs at the metamagnetic transition in such compounds. We find a large difference between the e...
